Everybody should know:
You can't be all things to all people
You can't do all everything at once
You can't do all things equally well
You can't do everything better than everyone else; you're human, just like everyone else.
You have to find out who you are and be that
You have to decide what comes first and do that
You have to discover your strengths and use them
You have to learn not to compete with others because no one else is in the business of being you.
You will have learned to accept your own uniqueness
You will have learned to set priorities and make decisions
You will have learned to live with your limitations
You will have learned to give yourself the respect that is due and you will be on the road to being the best "you" that you can be.
Dare to believe:
That you are a wonderfully unique person
That you are the only one just like you in all of history
That it is more than a right, it is your duty to be who you are
That life is not a problem to solve, but a gift to cherish
You will be able to stay on top of what used to get you down and achieve the impossible.
I saw this on Craigslist in 2006. Many variations on the web. No source found
