You are as happy as you make up your mind to be.
Make up your mind to be happy.
Mind is all that counts. You can be whatever you make up your mind to be.
You are about as happy as you make up your mind to be.
The time to make up your mind about people is never.
If you don't make up your mind, your unmade mind will unmake you.
You make up your mind before you start that sacrifice is part of the package.
