GSP recently did an interview with German MMA outlet GNP1.de in which he discussed everything from IVs to the current crop of fighters at 170lbs. In the above clip he talks about his current social life, his acting career and why he left MMA.
Speaking on the latter, part of what he said was: "I became world champion by training for fun. And then the fun became business, and business became stressful, and then you lost fun. I didn't have fun at the end, I did it because I had to, not because I wanted to. I should have actually stopped maybe one fight before, or two fights before, but I couldn't. It was always constantly another guy challenging me. Carrying all this weight on my shoulders, I felt like I needed to do it, instead of wanting to do it."
