On second thought, I'll just copy and paste the best part of the article:
It was my freshman year in dental school and I was broke. My parents were middle-class and didn't have much money left over after my dental school tuition and my brother's medical school tuition.
Then one day I received a letter in my mailbox. It was from the fertility clinic at the medical school, offering $75 for ... well, how can I put this.
For ... um ... my magic beans!
$75!
I began making some calculations. If I could give them magic beans once a day, five days a week, that's $375 a week, or $1,500 a month. That's plenty of cash to live on.
Then it hit me: If I get in shape and eat more Brussels sprouts, I could give them magic beans four times a day! That's $300 a day, $1,500 a week, and $6,000 a month!
In fact, I realized, I could quit dental school altogether and make a pretty good living.
And I'd still be working with my hands!
