Inspired by Andy Matuschak, I started dedicating an hour every morning during My morning routine to thinking. Specifically, I Write to think, which means I sit down in from of my computer and write anything I want to think through—which usually leads down many interesting rabbit holes.
This has been transformative to help me clear up my thoughts. Having a dedicated time for thinking is a big force multiplier for my creativity. (Invest in force multipliers)
