I give myself credit for stepping outside my comfort zone and working at a large intimidating place like Home Depot. Well, it's intimidating when you are in your 40s and have very little exposure to home improvement projects and tools.
Stepping outside ones comfort zone builds confidence and will help you to continue stepping outside your comfort zone.
Necessity is the mother of invention. With the price of a handyman, plumber, etc. so high - at least much higher after-tax than then for my old regular wagecuck job - I look to do everything myself, and only demur if it requires me to get on the roof or under the car trestles, or it requires plumbing-grade soldering, or it's just a royal PITA like when my hot water PVC pipe busted under my house (it froze up, LOL, but the cold water line was fine). I've replace wallboard, installed new toilet mechanisms, cleaned out clogged pipes, cut tree branches (via a 6-foot extension-pole chain saw), repaired soffit & fascia, spliced electric lines that had somehow broke (mice?), plugged gaps with foam. I've replaced an alternator before - although it's such a PITA on my current ride, a VW, that I think I would pay someone to do that - but replacing burnt out lamps, spark plugs or coil packs is cake. I've cleaned out window A/C units and have added coolant both to home & auto AC units. I've cleaned out an open-flame home heater. I've cleaned the metal parts on, and plan to tune, my piano. I once shimmed a door hinge for a plate because she had so many shoes hanging on it that the bottom was dragging on the floor, and the mechanic in me couldn't stand it. Oh, and then I have the hobby of working on pinball machines.
And everything can be learned on YouTube because for no matter what job you are looking to do, someone has made a video about how to do it.
