I dont consider myself very handy. But my father wasn't/isn't handy at all.
Then i worked in restaurants, did more gardening, started doing things here and there on the car/motorcycle like brakes, suspension, oil change, etc. Heck even things on my bicycle i didn't wanna play with
It's just so gratifying.
And with the age of youtube and the interwebs, there are less and less reasons to NOT do it. Where my in-laws are from, there was no "home builder" they built their homes, and that's just 1-2 generations (ie. my wife's grandparents). I learn a bunch from them and i feel less useless as a human.
Problem is, not a lot of people have access to those "resource" people to instill confidence.
Then you have the time factor too...
we got a family member to build our deck in the backyard... 14 x 16. Him and his wife do it for a living and they got here at 9, materials got tehre at 930, and they were completely done at 2pm
For a lot of people that would take weeks of doing a few hours here or there and figuring it out.
