Control Your Reaction

No matter how good you are at managing your life, you can't always control each and every situation you are in. HOWEVER, you can always control how you will react to each and every situation. 

You do not need to burden yourself with overthinking and overanalyzing everything and spend your days being paralyzed by allowing these to have power and control over you. You do not have to react to everything being thrown at you, even at the things that irritate you. Learn to isolate yourself from the situation and think if it will do you any good spending too much time dealing with it or just simply brushing it off and moving on.

Sometimes, the best way to deal with something is by doing NOTHING at all.
