Ok, I might as well go first: I wish I could draw. Not at the level where I could make photorealistic portraits, but I’ve always been envious of those who are able to scetch something together in a few minutes that perfectly captures what they want to convey. Sometimes words aren’t enough to express what I want to say, and for those situations I would love to have a simple drawing do the talking for me.
One thing that I have learned is that concentrating on something means doing it, whether concentrating on doing it right or wrong. So trying to not do something generally means doing the wrong thing because that is what I’m thinking about.
Doesn’t help with clumsy stuff that just kinda happens, but at least I stopped focusing on avoiding mistakes and then making those mistakes and reduced the overall number.
