What type of strength is this

Question

The strength that helps you not to quit and keep trying to achieve a goal?

Answer 1

You may be thinking of will power.  As it states it is the power to will yourself to do something.

Answer 2

mental strength really, because when you have a positive mind set, you can do anything you set your mind to. if you are really down on yourself, you can guarantee that you show that negativity in your performance! it is your own decision to push through the pain, and to work harder. you have to believe in yourself, and push yourself as hard as you possibly can. it takes a lot of determination to bite your tongue, and to take it. you have to be determined to perform to the best of your ability in anything you do, otherwise it is an opportunity lost. will power, mental strength and determination, are all parts of this strength

Answer 3

Hmm.. determination?
