Mahatma Gandhi
Strength does not come from physical capacity. It comes from an indomitable will.

Mahatma Gandhi
You can chain me, you can torture me, you can even destroy this body, but you will never imprison my mind.

Mahatma Gandhi
Don't talk about it. The rose doesn't have to propagate its perfume. It just gives it forth, and people are drawn to it. Live it, and people will come to see the source of your power. 

Zig Ziglar
Do it and then you will feel motivated to do it.

Charlotte Bronte
I am no bird; and no net ensnares me: I am a free human being with an independent will, which I now exert to leave you.

Edmund Burke
Neither the few nor the many have a right to act merely by their will, in any matter connected with duty, trust, engagement, or obligation.

Elie Wiesel
You shouldn’t act as a spokesperson for someone who’s trying to impose his will on you

George Eliot
Our deeds are like children that are born to us; they live and act apart from our own will. Nay, children may be strangled, but deeds never: they have an indestructible life both in and out of our consciousness

Henri Federic Amiel
Will localizes us; thought universalizes us. 

John Burrough
A somebody was once a nobody who wanted to and did it!
