Without wishing to oversimplify, it does seem pretty simple to me-- to be the person you want to be, start being that person. If you want to be different, change. If you can't change, then stop sitting around wishing you could. I don't mean unrealistic things, because it is true that I have not stopped wishing I could have wings and or a tail, but the things that are well within your range -- if it bothers you that you aren't a certain way, why aren't you working towards being that way? Or working towards not being bothered?
I want to be a person who clears deadlines, and so... I clear deadlines. I thought that I would like to be a person who can strike up a conversation with a stranger and enjoy it, but after having given it a valiant effort for a few years I concede that I am not that kind of person and it doesn't bother me anymore because anyway they invented podcasts so I do that instead and it's lovely. I sometimes think that I would like to earn more money at my job but then I remember that I had a job that paid me ridiculous piles of money and I loved that job, but when I stopped loving it I had to quit so I know that money is not as important as I thought it was.
I decided a couple years ago that I want to be the kind of person who says YES unless there's a really good reason to say NO. Curiosity killed the cat, but only after she got a good look. Last week, I was asked to go on a trip and I'm going because there was no reason to say no. I cracked my tooth and it got infected and I won't have time to fix it properly before I go so I expect this little adventure will be like an intensive spa -- all sunshine and no solid food. See you in 10 days, assuming I can't figure out how to post pictures while I'm gone.
