Happiness is the result of what you do.
You must first put something into your life before you can get something out of it.
Attitude, not Aptitude, determines Altitude.
Miserable people focus on what they hate about their life. Happy people focus on what they love about their life.
All of us perform better and more willingly when we know why we're doing what we have been told or asked to do.
If you go out looking for friends, they'll be scarce. If you go out looking to be one, you'll have all the friends you need.
