If you have the right tools then it's easier than ever. To put a different spin, a friend's father was a very successful auto mechanic. What he loved about it was the mental challenge of diagnostics. The stranger the problem, the better for him. A few years back he sold his shop. There were two reasons: 1) He made f** you money, and retired decades earlier than he'd expected. 2) For many years he'd felt like the daily intellectual challenge was gone. His repeated refrain was that modern self-diagnostic systems were good enough that it took away most of the day-to-day intellectual challenge.
