Your habits will determine your quality of life.
Motivation is motive in action.
The world is a mirror and reflects back your expectations. What you get is what you see.
Start edifying the flowers. Stop pointing out the weeds.
Expect to succeed even before you start. All winners, no matter what their game, start with the expectations that they are going to succeed. Winners say, "I want to do this and I CAN do this", not "I would like to do this, but I don't think I can."
The most important opinion you'll ever have is the one you hold of yourself.
