Aw man, it's been about 7 years already, and yet I feel like I'm not that much better compared to when I started. Sure, I know a good deal of stuff now I didn't back then, but I feel like everything I've learned in 7 years could probably have been learned in 2-3 years. I need to take action, make it so that I won't look back in another 7 years and say the same thing. But how? I find it difficult to find things to work on that feels both meaningful, but is not so hard that I'm unable to solve them.
