The way to happiness is: keep your heart free from hate, your mind from worry. Live simply, give much. Fill your life with love. Do as you would be done by.
25 “Therefore I tell you, do not worry about your life, what you will eat or drink; or about your body, what you will wear. Is not life more than food, and the body more than clothes? 26 Look at the birds of the air; they do not sow or reap or store away in barns, and yet your heavenly Father feeds them. Are you not much more valuable than they? 27 Can any one of you by worrying add a single hour to your life?
Jesus Christ Matthew 6:25-34 New International Version
“The great mistake is to anticipate the outcome of the engagement; you ought not to be thinking of whether it ends in victory or defeat. Let nature take its course, and your tools will strike at the right moment.”
― Bruce Lee
“If a problem is fixable, if a situation is such that you can do something about it, then there is no need to worry. If it’s not fixable, then there is no help in worrying. There is no benefit in worrying whatsoever.”
― Dalai Lama XIV
The man of wisdom is never of two minds; the man of benevolence never worries; the man of courage is never afraid.
