I have the opposite. My dad has always been truly awful at anything DIY. I just got on with learning and had a go, applying the few skills I learned in school, reading books then using the internet. I renovated 2 houses (1st one complete rewire, new bathroom, new kitchen, fully redecorated) with minimal assistance and learned along the way.
I’m renovating a house here in the USA now and that has necessitated I learn all about American construction/wiring/standards and re-learning my bloody 12 times table!
Pick a small job, watch a YouTube video or two about it, have a crack at it. Comfort zone gets bigger, jobs attempted get bigger, learn from mistakes.
