By being yourself! And it's much more to life then money and being rich. Be blessed with what you have! And try being successful in your life choices and riches will come to you... ( just a word of advice) good luck :))
Everyone is allegedly "cool" in their own way. It could be because of popularity, looks (not the way you usually want to go to gain popularity), intelligence, and personality. It all depends on how you behave and act around other people. Everyone is an individual and their own person, so be yourself! Good luck, and I hope I helped :)
How to be cool? Be you're self! God made everyone unique and awesome in a different way! :) You want to be rich? There s nothing wrong with that, you just have to take care not to get snobby and selfish as it is so easy to do when you have a lot of money, you want to trust in it instead of God. Mannatech is a very good business with no ketches that many people have been succesful with and it takes minimal effort once you have got it going, it is helping people world wide you can look it up on the internet. :) There is no age requirement.
Don't take life too seriously. Have a sense of humour. Have integrity. Be consistent. Treat everyone as you would like to be treated, with respect and kindness. Have goals .. reach for them, but without walking over anyone in the process.
Sit in a Refrigerator... You be very cool and that did not make you rich.. I you want to be rich, then find the best qualities inside you that what can you do perfectly and legally to start and grow your business.
