There is always an over abundance of free advice, but usually you get what you pay for. Unless of course you take the time to be observant and closely analyze the behavior of others.
Aristotle once said, "We are what we repeatedly do. Excellence, then, is not an act, but a habit."
I have often said that the most important life lesson I ever learned from my parents was, "Be nice to people and they will be nice to you."
That was of course a great lesson learned, but I can honestly say that they didn't actually tell me that, as much as they lived it out in their day-to-day lives.
They lived their lives by that theory as much as they could, and I can safely say that they have been rewarded with long wonderful lives.
So, watch and learn! You will learn a lot by being observant!
