It isn't what you have or who you are or where you are or what you are doing that makes you happy or unhappy. It is what you think about it.
You will never be happy if you continue to search for what happiness consists of. You will never live if you are looking for the meaning of life.

The moments of happiness we enjoy take us by surprise. It is not that we seize them, but that they seize us.
Happiness is a butterfly, which when pursued, is always just beyond your grasp, but which, if you will sit down quietly, may alight upon you.
The only thing that will make you happy is being happy with who you are, and not who people think you are.
The greatest joy in life is the conviction that we are loved; loved for ourselves, or rather, loved in spite of ourselves.
Happiness is not something you postpone for the future; it is something you design for the present.
Success is not the key to happiness. Happiness is the key to success. If you love what you are doing, you will be successful.

Don't wait around for other people to be happy for you. Any happiness you get you've got to make yourself.
