Today is my father's birthday and I've been thinking about the lessons he's taught me over the years. Here is one of them...
About 10 years ago, I had a federal lawsuit filed against me. I had one opinion about the situation and the guy suing me had another. My attorney thought we could fight it.
As you can imagine, something like this is pretty scary. I was talking it over with my father and he told me, "Don't die on this hill."
That doesn't necessarily mean that you should roll over and stop the fight, but even if you can win, realize that there is a price you'll have to pay. You'll use money, time, energy, and other resources that might be better used elsewhere.
In short, don't get caught up in "the priciple" and lose sight of the big picture. Sometimes it's better to walk away and use your energy and resources to create something brand new.
