The thinking that guides your intelligence is much more important than how much intelligence you may have.
Belief releases creative powers.
Get the action habit - you do not need to wait until conditions are perfect.
Believe Big. The size of your success is determined by the size of your belief. Think little goals and expect little achievements.
Goals are as essential to success as air is to life.
Think you are weak, think you lack what it takes, think you will lose, think you are second class - think this way and you are doomed to mediocrity.
