When I got out of MTSU with a CIS degree 8 yrs ago, I thought I'd be an IT manager by now. Instead, I gravitated toward one area and couldn't be happier that I didn't go the other route. I love what I do and that makes a huge difference.
The money being enough depends more on your lifestyle than your income. When I got out of school, I was making the same money I did managing restaurants for 15 years. The difference was I liked my job better, but increases in pay did come faster. I'd like to think that's mostly due to the enthusiasm that comes with loving what you do.
Whatever you do, don't chase the money. You'll be miserable! Instead, do what makes you happy and save all the money you can. Besides, a dual-income couple making an average salary can live very comfortably and not have to worry about money.
