I do think the heart can balance out the mind, if your heart is in a good place it can give you the strength to do the right thing and behave the right way and overcome the mind.

Will power is only the tensile strength of one's own disposition. One cannot increase it by a single ounce.

Strength is born in the deep silence of long-suffering hearts not amid joy.

Only actions give life strength only moderation gives it charm.

Let me tell you the secret that has led me to my goal. My strength lies solely in my tenacity.
