"In the end we only regret the chances we didn't take." So be risky because you would rather look back and say I can't believe I did that instead of I can't believe I didn't do that. I do regret that amazing chance that I didn't take.
For me, sleep isn't meditation. Sleep is an escape from the world. Sleep is the only way to truly not have any problems. Sleep is the only way to stop existing without dying. Sleep is a pause in time. Prayer is the best meditation.
