It took me a few rounds to detect this trick. I had a boss who would pick up on clues from upper management on where they may be headed. He would come back to our team, and throw everyone at a problem. "This is a priority for management.", he'd tell us. We'd solve the problem. About half the time, the solution would die right there, because management never requested it.
What he was actually doing was trying to guess what upper management wanted before they requested it. This way, when the request did come through, he'd have the solution on the spot. It made him look great. It wasted about half our team's time. One thing it did do for us is give us more experience in solving new problems, but at the expense of getting our day-to-day work done on time.
But I did get to the point of not being so eager to jump on his "call to action" meetings unless I had outside verification that it was an actual call to action by management.
I'm going to answer this assuming you mean gaining number sense, which is something I didn't realize I was missing until I gained it.
I got my undergrad in math and physics. I was good at math. It wasn't until I had been teaching high school for 3-4 years when some gave me a copy of Shortcut Math by Gerard Kelly. After reading it and practicing the techniques, arithmetic made so much sense. I was able to easily add, subtract, and multiply larger numbers in my head.
Interestingly enough, many of the techniques taught in this book are also part of the common core math curriculum. It's a way to help students gain number sense.
I've straddled and blurred the line between being in IT and an educator. I've seen home schooling go horribly wrong and incredibly right. From my observations of the few dozen families I've watched, it seems to mostly depend on the motivation of the parents, and how much time they're willing to put into it.
The ones that tend to go wrong are those parents whose primary motivation is to keep their children from learning things, usually on religious grounds. I'm not saying that parents who provide a religious education do a bad job, but if the goal is to avoid having kids learn certain basic level facts (like reproduction), they will have gaps. I've also seen where parents expect to throw their kid in front of a computer to do all their learning, which also goes bad. In these first few cases, I've seen situations that come close to neglect. A third path that can go either way are the single-issue families. This would be parents who want their child to focus on one specific talent in order to nurture it, like singing, dance, or a sport. In these cases, so long as there is other topics covered, the kids can turn out ok as well as be at the top of their field. There's also cases in this area that can look like abuse when the parent is a little too vested in their child's success.
The home-schooling stories that are super successful are usually where one parent (or ideally, both take turns) at turning every day activities into learning opportunities. One family took at least one trip per week to a museum, zoo, botanical garden, park, public government building, or conservation area. The kids had to research the location before the visit, write up a list of questions they had, had questions added by parents, find and record the answers during the visit, and write up a report afterwards. They would research an issue and write or visit government representatives to discuss the issue as a well-informed member of the public. In those families, it seemed the entire family was about daily and life-long learning. The parents also had the kids involved in a lot of outside activities like local plays, orchestras, sports. Just as busy as the public school kids, just a more holistic approach to learning.
I know a few truck drivers. They're not getting paid any more than in past years. Trucking companies may have increased demand, truckers are still getting paid trucker's wages. Enough to get by on at the cost of having to work 12+ hour days.
I inherited a large database that "supported" an application, when in fact the application layer was built into the database. I took over from a begrudging dev who was involuntarily transferred from dev/dba to just dev. In reviewing the hundreds of ETL jobs, I found one that started off as SQL that invoked visual basic script in an external file share, which at some point invoked a small obfuscated machine code script located on yet a different external file share. Googling didn't tell me what the machine code actually did. The disgruntled dev said that if I wasn't smart enough to figure it out then I should quit. He had put this mess together with the idea that it would be job security. Finally, his boss forced him to admit that the machine code stripped a text field of spaces. The job was re-written in straight SQL and ran much faster.
I heard a neighbor kid get hit by a car. A bunch of us were outside playing tag, heard the tires screech and the thump. The kid was an impulsive type, and the lady who hit him was our lunch room monitor, a very very sweet and kind woman. The kid was shooting across the road to check the mailbox, even though his mother had just told him she already picked up the mail. Other than the screech and thump, the only other sound I remember was our lunch room lady wailing when the paramedics stopped trying to revive him. We were half a block away observing, but is was like she was right next to me.
The kid was a grade or two below me, so I wasn't really friends with him. 40 years after the fact, that event still sticks with me.
I'll second Mendeley. I've used several other options, but Mendeley has a Chrome plug-in that will download the PDF as well as try to read author and other bibliographical info. The desktop app helps in searching for key words within all documents as well as individual documents.
I've done a bunch of little freelance stuff. Money is always great, and I'd follow the advice already given if that's what you're looking for.
On the other hand, it might be worth considering a trade for labor for whatever it is they sell. When I go this route, I usually end up getting way more in trade than I would have in cash. But again, this is only if they're selling something that you may want.
When I can't stomach puff pieces on NPR, I usually blame it in my extreme liberal bias, but still take in the information. I still haven't yet heard ANY in-depth stories taking Trump or Cruise to task for their many false statements. At the same time, I've heard quite a few stories on how Sander's policies aren't viable, or the number of ways Secretary Clinton may have broken the law by demanding a Blackberry phone.
An old co-worker of mine jumped ship in the way I wished I had. He had something like 16 or 17 days vacation, and he took every Friday off from September till the end of the year. He used those Fridays to look for new jobs and interviews.
I'm in. I'm currently teaching an undergraduate course in collaboration software, and I'd be interested to hear what others are doing, or what ideas they have.
