The secret of health for both mind and body
is not to mourn for the past,
not to worry about the future,
nor to anticipate troubles,
but to live in the present
moment wisely and earnestly.
In any moment of decision, the best thing you can do is the right thing, the next best thing is the wrong thing, and the worst thing you can do is nothing.
"You may believe that you are responsible for what you do, but not for what you think. The truth is that you are responsible for what you think, because it is only at this level that you can exercise choice. What you do comes from what you think."
