The item that struck me the most was: Everything you want to accomplish takes longer than you want it to take.
That's very true. Everything I've accomplished in life has taken much more work than I thought it would. Every year I've been writing (from day one), I've thought, "Oh, within a year or so, I'll reach the point where I'm selling almost every story that I write." I still am not even approaching that mark. At least 80% of what I write does not sell.
Stuff takes time and effort. People say that when you've earned something, you value it more. I'm not sure that's true. I feel like the things that I value most in life are the things that I don't feel I deserve. When I earn something, I feel like, well, alright, I deserve this. I made this happen. Like, I don't feel gratified when my computer boots up. It's supposed to boot up. That's what I bought it for.
Anyway, it's not a big deal, though, because (after awhile) the process of trying becomes fun in and of itself
