Been fired from 4 shops. Not sure what to do now
I'm 22 and I'm new to automotive. I started out in a tire shop last year as a GS. I'm green and only have a 2-3 months of experience professionally with no experience prior, but I kept getting fired, so I wasn't at each job for that long. I just got fired from my last job two weeks ago, and a recurring theme is that I work too slow, and I've had some comebacks over wheel balancing. I wanted to work on this, and my boss made me train with this flat rate tech that worked fast, thinking it would help me increase my speed but it wasn't enough, and in two days, I ended up being let go after 2 months.
I realize that I like working on cars and learning about them, but the auto shop experience and rushing to get multiple cars out for 8-10 hrs straight is not for me. My knowledge is growing, but I physically can not perform efficiently. It seems like it'll take much longer to get the hang of doing oil changes and tires under an hour. I want to work on cars, but this is killing my confidence. I think I'll have to switch to fleet or smth. I'm debating on going to school too, but for right now I'm taking a break. What should I do?
