“Ability is what you'ree capable of. Motivation determines what you do. Attitude determines how well you do it.” -Lou Holtz.
What are your abilities? Write out a list. Don't short change yourself, we all have a habit of undermining our own capabilites.
What's your motivation? Why do you do what you do? Motivation is a powerful thing.
How is your attitude? Could you be more optmisstic? Attitude is the most important piece of the puzzle. Without a good attitude, it's hard to get motivated to use your abilities.
