Don’t be in hustle mode all the time.
Carve thinking pockets in your day.
See where and how you spend your time.
Invest it where you can do less for more impact.
If you find it hard to slow down, go where it is easy to slow down.
Like in nature, because nature does not hurry, it has its own pace.
Until you can do that, be in the company of people who have a calming effect on you.
Also, meditate. Go for long walks.
And wake up early to have enough time to do everything you need to do. It helps because a no-rush life makes it easy to slow down.
