Be miserable. Or motivate yourself. Whatever has to be done, it's always your choice.
You and I are essentially infinite choice-makers. In every moment of our existence, we are in that field of all possibilities where we have access to an infinity of choices.
You can have anything you want, if you want it badly enough. You can be anything you want to be, do anything you set out to accomplish if you hold to that desire with singleness of purpose.
If you deliberately plan on being less than you are capable of being, then I warn you that you'll be unhappy for the rest of your life.
Abraham H. Maslow
Remember, happiness doesn't depend upon who you are or what you have, it depends solely upon what you think.
The only man who never makes mistakes is the man who never does anything.Theodore Roosevelt
