If You Got A Life, Sh!$ Happens
When your going about your day no matter how positive you are things will certainly happen as the world is full of separate individuals. So some days negative energy will cross you and throw a monkey wrench in your day. Realize the more you are out there the more energy you will come across increasing your odds of it being negative. Acknowledge that you not only have a life but that life is worth it and worth not getting upset about it. Your world and life is more important then the trivial frustration that goes on around you due to other negativity. You understand that you let go of frustration and only hold onto positivity and growth. Your life is worth being positive and not allowing other negativity to affect you.
