From the field
The same lessons come up again and again from people actually doing the job:
People think it's just turning spanners. Half the job is diagnosis — detective work tracing a fault to its root cause. Modern engines are full of electronics and sensors, so you have to understand the tech as much as the mechanics. Getting it right takes real skill.

It's an accessible trade — I did an apprenticeship, no degree — and it's always in demand because machines always break down. The work is satisfying too: someone brings in a vehicle that won't run, and you send it back working. Tangible results every day.

The path to self-employment is real. I started as an apprentice, built my skills and reputation, and now I run my own workshop. A skilled mechanic with their own business earns well, and there's always work. It's one of the most reliable trades there is.
