1. Use the same time for multiple things.
2. Create an asset
3. Do one nice thing every day.
4. Plan - Plan for those gaps in the schedule and make sure your work and rest is more intentional. White space (time to do whatever) is also great too, but make sure it's planned!
5. Routine - The highest performers in any field generally have a routine that helps put them into "game mode" and be ready for whatever comes their way that day. They go into the day "warmed up" and don't have to do that once they get there, because they are already ready.
