I like my job, but seriously struggled financially through my 20s, and after turning 30 recently, realized that I have to make some major changes to accomplish FI. The good news is that my only debt is 10K in loans, and I'm really good at living on about 2K per month...even managed to build a modest savings account.
I work in a field where career advice for graduate students often involves volunteering, and starting salaries(with a graduate degree) are not typically over 35K. I knew this when I went the "do what you love" route but I didn't realize the lifelong implications it would have to my personal/FI goals.
Considering that I've been working since I was 14, and worked through college, I am a bit burnt out on following "passion", and considering ways to make positive changes in my work situation. Seeing the range of case studies on MMM has put some of this in perspective, and its also reinforced the need for change in my career.
