I've always had issues with my height, but it was a bad breakup that really pushed me in the direction of doing LL. Even after the breakup and dating/hooking up with a pretty steady line of attractive women, I just still felt even more uncomfortable about my height than ever before (and I had many women taller than me asking me out).
I don't care about cars (I drive a f#cking 2009 Toyota Corolla for f*ck's sake, lol), fancy clothes, etc. - but I do value looking and feeling good about myself. So fitness and taking care of my overall appearance (I buy clothes I look good in, even if they're not top of the line brands) are important to me. I want to own proper someday too. But, in the back of my mind, even though I could clearly get women (and had more opportunities for long-term relationships after my breakup), I always felt like they would be "doing me a favor" (since I only date women I'm attracted to). My height was part of the reason I stayed in a long-term relationship with a girl who I knew in the back of my mind wasn't right for me. She was very attractive, and I had doubts I could get another attractive woman. I didn't want to feel like that ever again.
