Great system if you can make it work, but speaking from experience the physical medium of pen and paper was too limiting for me.
I found I had the most ideas/todos to note down when I didn't have my journal around me, at places like the gym.
Pulp Fiction. The combination of the upbeat music and memorable dialogue used to make me rewatch it at least once a month, as a feel good movie. I've since dialled it down but will still occasionally watch parts of it.
The funny thing is the first time I saw it I didn't like it all due to it's mixed-up order of story telling and, once you put it all together, fairly mundane plot. It was over time that I realised the plot is not really what you watch it for but you watch it for the overdrawn, yet interesting, character interactions in combination with the music and general vibe.
If it is supposed to be a meaningful link - be it internal or external - use a direct anchor element with an href. Styling it however you like shouldn't hurt.
Otherwise, for any other interactions use a <button> element
Also, if you like a particular movie/genre then it's best to google for similar ones. People tend to recommend 'if you like X then you should also check out Y'. I've found this to be a decent indicator.
AFAIK, dark mode can save energy on OLED based screens (due to pixels being completely turned off) but not on LCD-based screens. However, lowering brightness should probably always lower energy usage.
Speedsolving - solving rubik's cubes and similar puzzles and doing it FAST, blindfolded, one-handed etc
Sports/workouts/exercise - not original but great way to balance the sedentary lifestyle if you're not already doing so
Juggling - pretty fun to learn and relaxing activity. It has been shown to give great mental benefits when done regularly
Card tricks/magic tricks - impress your friends during parties
Learning foreign languages - this one has so much in common with learning programming I'm surprised that it's not that popular among developers. It is quite mentally draining tho so combining it with programming career is hard
This is exactly my dilemma. I've been in the industry for 2 years but done very little personal development in my own time and my job has been quite limiting in pushing my skills in the direction that I desire.
I value my after work hours to pursue other things/exercise/have a life. This makes me put even more thinking into how should I be spending my already limited time.
Currently I'm sticking to doing some MOOCs related to my my development path (Android) and then I want to crack on a few personal projects. On the other hand, the clock is ticking and I really would love to prepare well for better career opportunities...
I always think that it's only a matter of time before some company with vast capital (looking at you Apple) finds their own way to set up a city/country with their own ecosystem (healthcare, transport etc.), with less bureaucracy and more efficiently.
