We over-exaggerate yesterday. We either think it was better or worse than it was - you know, the good old days. We over-estimate tomorrow; we think we can do more than we can - always. And that's why we put off everything till tomorrow.

It is hard to feel bad about yourself when you are doing something good for someone else. There are a lot of ways to lift your self-esteem, but making a positive difference in another's life has got to be my best leadership guidance. Serving others and working to add value to them will lift your spirits in a way that nothing else will. Trust me on this one.

When I was 17, I made the decision to have a good attitude. I was a junior in high school; the coach said I was going to be the captain of my basketball team. I thought – that surprised me because I wasn’t the best player. John Thomas was better than me, and I was probably second or third best player. And I kept thinking, “Why am I going to be the captain?” I think everybody else was thinking that too. And the coach then answered, “The reason John is going to be the captain is he has the best attitude on the team. He encourages others, he believes we can win, he never gives up.”

If you're not failing, you're probably not really moving forward.

Mistakes are the stepping stones to success.

Every worthwhile accomplishment has a price tag attached to it. The question is always whether you are willing to pay the price to attain it - in hard work, sacrifice, patience, faith, and endurance.

Even if you've had a negative effect on others in the past, you can turn that around and make your impact a positive one.
