You can't talk defeat and expect to have victory. You can't talk lack and expect to have abundance. You've got to send your words out in the direction you want your life to go.
If you cannot be positive, then at least be quiet.
If you want to be happy, you have to be happy on purpose. When you wake up, you can't just wait to see what kind of day you'll have. You have to decide what kind of day you'll have.
Happiness is always a choice. You can't wait for circumstances to get better. You have to create your own good fortune. So look for ways to be happy every day.
