The most important advice

1. Treat others the way you would like to be treated

This is even more important as you achieve more and if you are in positions of power.

2. You can do anything (within reason)

With a great deal of hard and smart work you can do almost anything. Professional sports and traditional high fashion model might be the only caveats.

3. We don't all start at the same place, but you can overcome a lot

To push back on #2, look at this young man for inspiration. If he can be this good at wrestling what are you capable of that you are telling yourself "I can't."

4. You are not a victim

If you are born in the western world, you don't have much to complain about. If you are whining that you didn't grow up with more money, or did not go to the finest schools, look at the young man above for inspiration.

There are real problems in the world. Not getting into the school you wanted or not getting the job you want is not a real problem. Bad things do happen to good people, unfortunately.

Not only that, most of the uber successful overcame A LOT. It make the journey much more satisfying.

If you are born on third and get to home plate is that better than just hitting a double? Be proud of yourself. Don't waste much time complaining.
