"It's not the daily increase but daily decrease. Hack away at the unessential." - Bruce Lee
If you want to improve your life then it’s tempting to want to add more. One problem with this may be that you don’t really have the time or energy to do more though.

Removing clutter and activities, tasks and thoughts that are not so important frees up time and energy for you to do more of what you really want to do.
