"The winners in life think constantly in terms of I can, I will, and I am. Losers, on the other hand, concentrate their waking thoughts on what they should have or would have done, or what they can't do"

This quote by Denis Waitley talks to the power of positive thinking and the value of having a growth state of mind. It recommends that those who succeed in life have a positive outlook and focus on what they can do, instead of what they can't. They believe in terms of "I can, I will, and I am" and do something about it to make their dreams a truth. On the other hand, those who are not successful tend to dwell on the past and focus on what they need to have done or can't do. This type of thinking can be destructive to success as it avoids them from taking action and achieving their goals. It is very important to concentrate on today and what can be done in order to be effective.
