"Decision of Character"

“All difficulties which might and would cross our way must be surmounted. Though the soul be tried, the heart faint, and the hands hang down, we must not retrace our steps; there must be decision of character.”  Joseph Smith

What does it mean to have “decision of character” when facing difficulties?

I really liked this quote.  It would be great if all of us associated with Esperanza--educators, scholars, Board members, etc. learned to make decisions of character.
