Hey! I like your user name. That's pretty clever.
I am right there with you. I was a small business owner, but Gave it up to Get back in school and pursue a more passionate career choice/life purpose.
My business was a service business that had me leaving the house early in the morning, driving all over the city, and getting home late at night. I was eating crap, my body was stressed, and my mind was a little "sick." It had to go.
Luckily, I was in a position that allowed me to make those life changes. There was sacrific, for sure. But I would make the same choice again and again if the same situation was repeatedly presented to me.
By changing my career, I stopped driving around the city all day. This helped my back and knees - which hurt from sitting in 6 hours of traffic.
I stopped eating fast food - I am no longer feeling rushed, I now have time to make a meal that is healthy and much better on the wallet.
I realized that chasing the dollar is not my life purpose. Many people try to tell me that I should be chasing the dollar, the American dream - No thanks. There are many more healthy/entertaining things to chase than the perspective that money buys happiness.
The best thing I learned is that I should chase what I want to chase, and let others race their own race.
Sometimes it's good for a change. Other times it isn't.
