Money is not everything. You have your way of life, they have their. Don't judge anyone by his wealth. Of course not to judge yourself this way either. Do you believe that the workload and pressure for earning $30,000 and $10,000 are the same? If you want to be a professional, it is never too late to study.
Love yourself, enjoy the moment you have, appreciate what you have got. Strive for the excellence.
