No matter your lot in life, remember to never be vain with what you have or jealous of what you don't have.

Nobody likes a vain person.

You never feel above or better than another human being because of your house, your bank account, your car, your job, or your title. Be proud of what you earned but leave vanity for the less educated. Use the value that you bring to this world as your measuring stick. Always bring more value and improve the lives around you with your success. Be charitable. Lift other around you with your good fortune. There is no better feeling in the world that to help a fellow human being to the point that they smile.

Don't be jealous of the house, money, car, or station in life that somebody else has.

They worked very hard to get there. That person does not owe you or the world anything. And if you want their station in life then you need to work as hard or harder to attain what they have. Use them as a role model. Ask them how they did it and if they will help you do it. But jealousy will make you a bitter and hateful person. And it robs you of the time and energy you need to improve yourself.
