Mature students (+ 26 y/o), what made you quit what you were doing and "go for it"?

I was unhappy. I have a degree in business, and was working for a marketing company, while living in Manhattan. I hated it in New York, but the girl I was seeing(and truly loved) lived there and so I moved my life to be with her. I took this job because living in New York is expensive and even though it involved me traveling a lot, it paid very well. After a while I proposed to this girl, and even though I wasn't enjoying living in NY, I was happy to be with her. Not before long she thought raising a family in New York wasn't a good idea, which I totally agreed, so we ended up moving to the west coast to be close to her family. Thing is, even though I could work a little from home, all my clients and work was on the east coast. I had to travel even more and be longer away from my fiance.After about 6 months from moving, I noticed my fiance was becoming more distant, and then she completely shut off from the relationship and we ended up separating. From the stress from work and my love life falling apart I ended up gaining weight(mostly from takeout from traveling so much) and was just generally unhappy with myself. I realized that I hated what I was doing and the reason for doing it was gone. I knew I needed to work on myself and get into something that I would love. I started as an engineering student, the first time around. I didn't have the fortitude and discipline to complete it so I took the easy way out and got it in business. Since I gave so much for the relationship, I decided I was going to become selfish and give to myself this time. I needed to work on myself and be happy with who I am. I started going to the gym, and since I had residency now in Oregon, I chose to got back to school and finish this time here. I'm down 40 lbs, have a 4.0 major GPA, just got accepted to the Pro school two days ago, and loving life right now. I wish sometimes that I was closer to family and friends, but then I realize that with most of the studying I have to do, I wouldn't be able to spend much time with them anyways. It sounds corny but I finally like me again, and couldn't be happier with the way my life is right now, even though I'm studying mechanical waves and fluid dynamics on a Saturday night, which I know most of you guys are too for your respective classes.
