Don't let others project their misery onto you.
People that can not control you physically will attempt to manipulate you emotionally and mentally. Happiness is an inside job, don't be fooled by outside forces.
No one can control the actions of others, but you are always in control of your reaction and response to them.
People will try to bury you in chaos, don't suffer in the dirt, grow from it and flourish.
Sometimes the best response is silence and the best revenge is success by way of inner peace and happiness.
Misery loves company, so don't answer the door if it comes knocking!
