Don't fight too much. Or the enemy would know your art of war. Aim for the moon. If you fall you'll be among the stars. The only job you start at the top is when you dig a grave.
All arguments have two sides, but no ends.
If you don't stand for something, you'll fall for everything. If you do little things well, you'll do big ones better. Only thing that comes to you without effort is old age. Promise only what you can do. And then deliver more than what you promised.
