Trust in your own beliefs or succumb to the influence of others'.
When you think a positive thought, you become positive.
See it first in your mind, then become it.

Share your aspirations only with those who will support you, not those who will respond with doubt or lack of interest.
It is true to say that the secret of a winning formula is the ability to accept that there is a vast area of unexploited potential beyond what you currently perceive to be your maximum.
