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.
I’ve found that people who worry that they have bad handwriting typically have very good, legible handwriting. This is true with a lot of things actually. If you care about it, chances are you’re above average already. It’s only people who don’t care and thus you don’t hear from at all about it who are truly bad at something.
