yeah my dad made me learn all that shit at my uncles old house.
was worth it, if you have kids and are reading this right now, teach them to fix stuff, its a gift that keeps on giving.
I'd add basic mechanics to this list -- things like changing my own oil and replacing my own battery have saved me a TON of money and there's a satisfaction that comes from being able to fix your own stuff.
As an aside, my wife and I do home improvement projects 'for fun'. Our largest so far was updating a bathroom. Youtube is amazing for learning, and worst case you end up hiring someone to fix what you broke :)
