What is strength?

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

If we have a strong will and persistence that cannot be overshadowed by temporary setbacks and disappointments, then I believe we are capable of achieving the goal(s) that we set for ourselves. Sure, we may have to deal with difficulties, failures, and other roadblocks along the way, but as long as our inner will and belief in ourselves and positive outcome are strong, then eventually we will accomplish that what we want in life.
