Focus is selective neglect. You can’t have it all.
Every hour spent on building a career, is an hour you can’t spend at the gym, or with your family.
Try to do it all, and you’ll likely fail at all.
Knowing this should make you feel relieved. Relieved from feeling bad when you succeed at one thing, but fail at another. It’s part of life.
Just make sure that the few things you focus on are the things that are most important to you.
