I really appreciated this checklist that Elder Lawrence E. Corbridge provided in an article from the September 2011 Ensign:
"You are valiant if you:
- Keep on going when you think you can't go anymore.
- Admit your mistakes and strive to be better.
- Pick up the scriptures and put down the TV remote.
- Tell the truth when a lie would be easier.
- Refuse to do wrong even when everyone else is doing wrong.
- Set aside personal interests and/[or] postpone education to serve a mission.
- Speak no ill of another.
- Are honest even when it seems that no one else is.
- Choose not to click on a pornographic site.
- Smile and help another even when you yourself need help.
- Exercise self-control.
- Pray with all your hearts.
- Forgive.
- Strive to raise your children in light and truth.
- Share the gospel without regard to consequences.
- Remember the Lord and keep His commandments.
- Don't count the cost. "
