When I think back to how I got started doing stuff, I think it started when I was a teen and it was just me and my mom. She was going to pay this guy down the street what I thought was too much money to install two ceiling fans with adjustable speed switches. My mom traveled for business sometimes and once while she was away overnight, I opened the box, read the instructions and followed along. I was able to install two ceiling fans with those switches by myself while she was gone. I don't remember it being traumatic. I do remember her coming home, absent mindedly flicking the switch and the fan came on. Once she realized, she was upset that the man was in the house alone with me. I told her I did it. Then she got mad that I could have been electrocuted. I told her I cut the power by turning off the breaker. She swayed between anger and being impressed. Also, my grandpa build garages on the side from his regular job and he never once told me to go away when he was in the garage doing stuff. Nor did my dad. I'm trying to teach my kids, my daughter is interested. My son thinks robots will eventually do it all or apps....
Fast forward...I got a job working on a small family crew doing renovations and such. I knew a lot already but I learned a lot more having someone teach as we worked. I think I just have no fear of trying something. I'm currently remodeling my bathroom alone. Was stymied by an injury then loss of income.
As for tools, I find that Craftsman brand has smaller handles for me to use. I love DeWalt but their stuff can be too big for me to handle efficiently. If I do find tools "for women" they are usually pink, not at powerful, and stupid.
I ended up running a lot of wire, I enjoy doing the "inside wireman" work. While I was on that crew, there were some things I just could not do. I was limited by my size. Hanging drywall on the ceiling was something I gladly opted out of. However, because I was small, I did get shoved into a lot of holes to run wires.... you win some, you lose some.
I find that just jumping in is the best way to learn. I buy tools as I need them. Just bought a "hand held" 55# demolition jack hammer. That might be a bit much for me but we'll see. I have things to do and I can't let my size stop me.
