It's not about how much you make, but how much you keep. Who would you rather be: A professional athlete who makes $500K a year and spends $501K a year or a teacher who makes $20K a year but only spends $15K? Personally, I would rather be the teacher. Yes, the athlete probably has a nicer house and car than me... today. However, that extra $5K can be invested and used to create even more wealth. Imagine this: you invest that $5K and earn a nominal return in a retirement fund. At the age of 65, you'll have enough money saved you'll NEVER have to think about money again. As a matter of fact, you'll have well over $1 million (if you start at 30 years old) in your account. That athlete, who never saved, will only be up to his/her ear in debt. Chances are that nice car and house will disappear.
Now if you're like me, 65 years old sounds like a long time to wait. What if you could earn better returns that 10% annually? What can you do that adds value to people's lives? There is no right answer, but think about this for a minute. The majority of millionaires in the US are small business owners (we're talking 97%). The other 3% percent are athletes, actors and inheritance benefactors. Also, the majority of millionaires are ... surprise surprise ... teachers. Teachers know how to live within a budget and enjoy a nice chunk of time during the summer to operate their business.
So, as nice as it might be to be a superstar athlete, it's not about how much you make. It's all about how much money you save, and how you figure out ways to have that money work for you.
