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.
Being able to do stuff without having to mentally prepare for days/weeks/months and then abandon it because it’s just too much. I want to travel more, go on multi-day bike tours, start a business, whatever. It’s almost impossible for me because I worry too much about every single detail that could happen.
