It basically means that when you feel everything pressured on you, you just need to stop and relax. Live in the moment you're in, enjoy life. Yes, I agree with this quote. You can't always be stressed about something.
If you try and control everything, than you can’t stop to look at the world around you. You won’t enjoy life for what it is. Sometimes people don’t like it when others control everything. You gotta learn to slow down, enjoy life, breathe air, and don’t forget to have fun!
