"When you complain, you make yourself into a victim. When you speak out, you are in your power. So change the situation by taking action or by speaking out if necessary or possible; leave the situation or accept it. All else is madness." Eckhart Tolle, The Power of Now.
"Don't downgrade your dream just to fit your reality. Upgrade your conviction to match your destiny." --- Reality: what you see with your eyes now is a past creation and that doesn't have power to create future. So dream big! Everything stars from within.
Holding onto suffering is self-inflicted pain. Let it go and you will grow into a person that can help others who have endured the same sufferings you have. Holding onto it keeps you from your future and your purpose in life. There's a purpose in pain.
