What do you mean 'balance'?

And why do I care?

Fair question.

Think about your life for just a moment.  How it's been up til now was created by all the opportunities we had/didn't, choices we made, and how we reacted to them.

We can't do much about whether or not we have opportunities, but we sure can make better choices, and hopefully react better, so we can have a better tomorrow than we had yesterday.
