"The remarkable thing is that we really love our neighbour as ourselves: we do unto others as we do unto ourselves. We hate others when we hate ourselves. We are tolerant toward others when we tolerate ourselves. We forgive others when we forgive ourselves. We are prone to sacrifice others when we are ready to sacrifice ourselves."
- Eric Hoffer

Response to question on discipline by LifeLessonsForAll.com's LessonsAsk...

Question: How do I improve my discipline?

Response:
Just like exercise gradually improves body tone and muscle, practicing control, restraint, and willpower improves a person's discipline. Discipline is control - the ability to control one's desires, the ability to say no, the ability to persevere.

"Mental toughness is many things and rather difficult to explain. Its qualities are sacrifice and self-denial. Also, most importantly, it is combined with a perfectly disciplined will that refuses to give in. It’s a state of mind – you could call it character in action."
- Vince Lombardi
