Making space for happiness.
Being a pro doesn't mean working all the time. Rather, working all the time is a sure shot sign of an amateur. When we work all the time, we tire ourselves out and don't ship much.
The pro sets boundaries so they can make space for other things in life. Space to hang out with friends, space to take care of their health, space to relax, space to do nothing.
When we make appropriate space for things in our lives, we make space for happiness.
