I envy the people who can endure the drudgery and boredom of most jobs, and can therefore have stable longterm careers.
I've had a stable, long term, stress free, career working at large 'boring' companies doing high level research projects with very smart people in areas I find fascinating, and that I'm still excited to get to work on. 'Boring' and 'stable' companies still have very cool problems they need to solve.
You make it sound as if chasing ideas is the hard part, but for some people the opposite is the hard part.
