Problems you want to obsess about

When you have the luxury to choose what you work on, work on problems you want to obsess about. Problems that you’ll want to stay up late or wake up early for. Problems that will make most of the trade-offs that come your way feel worth it.

Say no to things that don’t meet that bar.

This strategy won’t necessarily maximize money or fame. Instead, it’ll maximize excitement, engagement, and joy.

In the long run, these end up mattering more than the other stuff.
