+1, though I'll add it doesn't need to be a completely "non-chill" job.

Your job should be manageable day-to-day with certain period of stress or extra work where you need to push yourself. This is where growth occurs.

Example: You need to learn a new language/framework and maybe spend some extra hours outside of work for a few weeks to ramp up for a new project. But once you have a handle on it, you go back to your regular schedule. And that might even mean now you can relax and work less than your regular schedule. It's all about managing when you grind and when you "coast".
