I always have a problem in mind while in college, and the problem becomes my real problem. If my day job requires me to work from 9am to 8pm, excluding 1 hour round trip commute, which is a norm in the city I am living in, how can I squeeze out time to maintain a meaningful github repo/ SO profile / tech blog? I really want to sharpen my skills AND display it, but my day job already take up literally half of my life.
