ATTITUDE
Happiness is an attitude of mind, born of the simple determination to be happy under all outward circumstances.
So long as you've got your friends about you, and a good positive attitude, you don't really have to care what everyone else thinks.
If you go on stage with the wrong attitude, or something in your performance is off, you can lose an audience in the first minute. That first minute is crucial.
You may not be able to change a situation, but with humor you can change your attitude about it.
Choosing to be positive and having a grateful attitude is going to determine how you're going to live your life.
