So today my car battery died, couldn't even be revived with a jump. I was able to walk to an auto store to get tools and a new battery (damn that mfer was heavier than I expected). I had never had to replace my own car battery before.
I screwed the fastener nuts the wrong way for like 5 minutes, cut my hand, and ultimately accidentally crossed the positive and negative terminals with a wrench that exploded in sparks. I don't even know what stopped me from being electrocuted but I didn't feel a thing.
While I'm happy I was able to take care of it myself and will be able to in the future, I also feel like such a dunce for not knowing wtf I was doing and almost shocking myself
Absolutely this on confidence. The first and most essential step is letting yourself be someone who can solve the problem. Next is being careful about it, sure.
Another big part is just careful attention to the parts available, as a huge number of intimidating problems (especially in plumbing) are solved by carefully browsing the catalogue and following up on the leads it offers.
