Working in an industry/space in that industry which you genuinely believe in +

Having the skill to compete competently +

Having a magnificent pay/payout

Although these days, asking an AI to do some low-level but complicated task and seeing it done ten times as fast as you could do it by hand is also quite satisfying.

I've found it's when you finish programming, and get to use your new code to accomplish what you set out to do with the electronics that you couldn't do before.

Being in the flow state.
