Strength does not come from physical capacity. It comes from an indomitable will.
Courage is not the absence of fear but the ability to carry on with dignity in spite of it.

The only limit to our realization of tomorrow will be our doubts of today.
It always seems impossible until it is done.
The greatest glory in living lies not in never falling, but in rising every time we fall.
The difference between a successful person and others is not a lack of strength, not a lack of knowledge, but rather a lack of will.
Perseverance is not a long race; it is many short races one after the other.
Our greatest weakness lies in giving up. The most certain way to succeed is always to try just one more time.
The only thing standing between you and your goal is the story you keep telling yourself as to why you can't achieve it.
The only person you are destined to become is the person you decide to be.

Resolution is the youngest and boldest daughter of hope.
Success is not final, failure is not fatal: It is the courage to continue that counts.
You are never too old to set another goal or to dream a new dream.
The only way to do great work is to love what you do. If you haven't found it yet, keep looking. Don't settle.
Believe you can and you're halfway there.
The future belongs to those who believe in the beauty of their dreams.
Our greatest glory is not in never falling, but in rising every time we fall.

It is not enough to take steps which may someday lead to a goal; each step must be itself a goal and a step likewise.
In the end, it's not the years in your life that count. It's the life in your years.
In the confrontation between the stream and the rock, the stream always wins – not through strength but by perseverance.
