Back in 2010, Todd Schnick approached me with an idea about writing a short e-book about what it takes to succeed in business—and in life. He called it “40 in 240, the intrepid mini-MBA project”. The premise was 40 people would share their advice to MBA students and aspiring young business people in 240 words or less. While some of the references are dated, the advice holds up well.

Here’s what I wrote.

As a child, you enthusiastically told anyone who would listen that you were going to be an astronaut, doctor, or rock star when you grew up. We all did. Yet, in 2010 the most popular careers in the US are: network analyst, physician’s assistant, medical assistant, health information technician, software engineer, physical therapist aide, fitness trainer, database administrator, veterinary technician, and dental hygienist. Seriously, who dreamt of being a database administrator? The shrewd reader also noticed that 60% of the careers listed above are subordinate roles. Shrewd reader, is it your passion to be an accessory to someone else’s dream? I think not.

Somewhere between the wide-eyed avidity of youth and adulthood’s discovery of the “real world”, something regrettable takes place. People let pragmatism guide decisions, and override zeal. They lose touch with their passion. Don’t let this happen to you.

I’m not advocating everyone pursue rock stardom or space exploration, but to listen to the voice of passion inside you. You hear it already, you need to listen. There are many articles on finding and following your passion. Read them, find it, and follow it relentlessly. There is no greater satisfaction than succeeding at something you truly enjoy doing.

If your quest is to become rich, your success will be empty. If your goal is to be famous, your fame will be lonely. But, if you follow your passions to greatness, your wealth and satisfaction will be endless.
