The only focus you should have Is on yourself, not the people around you.
It doesn’t matter what they have, or what they do.
It’s ok to have curiosity in them. But leave It that. Don’t let it become an obsession that consumes you where you’re constantly thinking or worried about what they have and what you don’t have.
The more you worry about everyone around you, the less you’ll be able to focus on yourself and what you can do to learn, improve or change so you can have more in your life.
