You must continue to gain expertise, but avoid thinking like an expert.

Understand that you, yourself, are no more than the composite picture of all your thoughts and actions. In your relationships with others, remember the basic and critically important rule: If you want to be loved, be lovable. If you want respect, set a respectable example!

Optimism boosts your energy and focuses your sights on reaching your goals, rather than wallowing in your setbacks.

Success is almost totally dependent upon drive and persistence. The extra energy required to make another effort or try another approach is the secret of winning.

Perseverance does not always mean sticking to the same thing forever. It means giving full concentration and effort to whatever you are doing right now.

If we succeed without sacrifice, it's because someone sacrificed for us.

Highly motivated achievers are looking not to receive but to contribute. They are looking for problems that are personally satisfying to solve.
