Talk health, happiness, and prosperity to every person you meet.
If you can't speak of good things, remain silent. Avoid gossip above all. This is a tough one sometimes, but refraining from it makes a big difference.
Consider: What is it about the next minute, the next week, the next month, the next year, or the next five years that would make you happier than you could be right now?
In all truth, the only thing we really have is the 'right now' moment. That's where the real joy, the real peace lies. Take a deep breath. Relax. Be here now!
