Sometimes when we can't let it go, we just have to let it be. Sit back as an observer of your thoughts, and let them ebb and flow as you listen to them and learn from them. Don't make friends or enemies with your bad thoughts, make peace with them.
"The moments of greatest joy appear while you forget to expect anything." Lama Ole Nydahl
Great opportunities are not seen with your eyes. They are seen with your mind.
Consistency is critical. Be consistent in your studies, in your workouts, with your attitude and personality and everything else you do in life.
