I came to a similar conclusion last weekend. My 20 year old car was having some issues and instead of taking g it to the mechanic to be charged $1,000, thought I would give it a try myself. 3 hours later and the problem was fixed. And I learned a lot in the process.
YouTube has been a godsend for these types of problems. It's like LLM output, you need to validate and cross reference but combined with other sources of information, easy purchase of parts and problems that actually have solutions (vs "buy a new one") I've saved thousands on cars, appliances and home repairs
I had the same with my motorcycle. Every time I brought it to the dealer, they came up enthusiastically with things to spend money on. Your tires are done! Your break pads are gone! With the help of a friend, I got into doing (very) basic maintenance myself. I just replaced the tires. I fixed a problem with the electrical system. And next will be the chain and sprocket.
That's why I do all DIY myself, incliding plumbing or electrics. Craftsmen cost money and they try to finish in one session, so they do lots of compromises.
Examples: under a sink, there were two 2m-long supply hoses, where 40cm would be enough, convoluted in a double loop together, to spare a visit to a DIY store. Or dowels made to be driven by hammer, for plastic baseboards, used to hang a cupboard (almost fell out). Or a too long corrugated plastic tube making a virage and another, unnecessary, water seal, and impeding outflux -- also to spare a visit to a store.
