Biggest learning from my first year working: I always had a few tasks on my to-do list that I kept putting off. I have procrastinated a little bit in high school, but overall I'm usually pretty good about getting things done. I didn't know why it took me so long to get some of these things. Looking back, it became obvious that there was some emotional component that I attached to the tasks. And it was that emotion that stopped me from doing them.
I was doing two things. The first, was taking on tasks that I didn't know how to do. That meant that, at least for the first few hours of doing them, I would suck at them. Them. That was something I just need to get past. Was taking on tasks that I shouldn't have been. Sometimes this meant offering to do something that I shouldn't have.
