Learn git. Contribute to open source projects - you may learn more from code review on a single PR than from a whole tutorial. Ask questions constantly. Learn more git. Look for the cleanest solution to a problem. Write code that is easy to improve, easy to expand, and easy to debug. Learn even more git. Don't limit yourself to thinking only in terms of OOP, or functional, or procedural, or whatever type of programming you may be comfortable with. Don't be afraid to do some work by hand. Learn git, so that when all comes crashing down and your team crumbles to pieces, when your relationships fail and your friends disappear, when you're down on your luck and there truly is no hope left in life, you can check out of the dangerous world of your current HEAD and return to the home and comfort of your master branch, which you've kept safe, secure, and functional.

Thank god for the squash and merge feature on github... 1/3

Instead of actually fixing bugs, most of my latest PRs have been adding "debug features" that make me look productive but really just enable my total unwillingness to actually fix the bugs.
