You may have to fight a battle more than once to win it. If you don't invest very much, then defeat doesn't hurt very much and winning is not very exciting. The difference between a mountain and a molehill is your perspective. Nothing great was ever achieved without enthusiasm. An army of sheep led by a lion would defeat an army of lions led by a sheep.
Worry takes as much time as work and pays less.
What's right isn't always popular, what's popular isn't always right .
