The great philosopher Marcu Aurelius said, “You have power over your mind – not outside events. Realize this, and you will find strength.” His point was that focusing on things you cannot control causes you great suffering. So here are the things you should focus on:
 

• The way you perceive the world.
• The way you treat others.
• How you act.

 
Make these choices each day, with each interaction and relieve yourself of a great deal of stress.
