I don’t want to pressure you to become an expert at anything, but I do want you to become good at something, which I think requires far less time and dedication. So here is my 1,000-hour rule, a much gentler version of the 10,000-hour rule: I claim that it takes roughly 1,000 hours of practice to get good at something. 1,000 hours of practice over a decade amounts to roughly 2 hours each week, which is far more sustainable than 4 hours each day. Surely you can spare 2 hours each week for some hobby. So find something you genuinely enjoy doing for its own sake, stick with it, keep learning more about it, and after a decade or so, you can’t help but get good at it and feel proud of yourself.
