The power to hold on in spite of everything, to endure, this is the quality of a winner. Your greatest glory is not in never failing, but in rising every time you fail.
It's your constant and determined effort that will eventually break down all resistance and sweep away all the barriers before you. Persistence means taking pains to overcome every obstacle, to do all that's necessary to reach your goal.
All great achievements require time. It's never over until you say it's over.
