No matter who you are or what you possess, each and every one of us have our own battles to fight. You may be good with family, but terrible in business; you may be great at making money, but can't seem to get yourself to workout and stay healthy; you may be excellent with people, yet find it hard to keep your relationship in order. Whatever it is, we all have our strengths and weaknesses, and we are all here to help each other achieve a satisfying balance.
Even good people can make bad decisions or become desperate when push comes to shove; even well-intentioned people can find themselves in disappointingly tempting situations. As long as we are here, we all live under the same Universal Law of Impermanence, that is to say, nothing is permanent — the only permanence in life is change. You could have it all one day and lose it all the next. Nothing is ever for sure.
So do not pass judgments. You may very well be one of those "good people" who say "that would never happen to me" or "if that were to happen, I would never...". I've come to learn that you can never say never unless you were actually faced with that exact same circumstance you are referring to; you may be suprised with your own actions when desperate times call for desperate measures.
So let's face it, no matter your age or status, you will make mistakes; you may repeat mistakes; some of you still don't get it; some may get a few things "right" sooner than later; but eventually, most of us will get it "right" enough. To live a life in harmony would then be to observe with compassion. It would be wise to not look down on someone unless you're helping them up. Remember: Judging a person does not define who they are...it defines who you are.
