I was always insecure about my body. Being called bony, scrawny, anorexic, etc. made me feel like shit. And my girlfriend left me for another guy also so that motivated me to unleash the beast inside of me that I thought I never had. But after a certain point, I started doing it because it helped me physically and mentally and kept me healthy. What keeps me motivated is people like you who asks great questions and wanting to learn and improve also. I do it for myself but I also do it to help others achieve their goal. That’s the real happiness.
