This is not reddit. More moderation please.

To make it more general:

"Find your hobby, or try things until it finds you. You will probably be surprised by what you find gratifying and it will almost certainly be oddly specific."

Apparently this is a suggestion for a relevant(?) subreddit, but a bit more context would be nice

Well, I would suggest learning how to make Straight Bevel gears, but that's too specific and autobiographical.
