What was your motivation then to do LL?
I have achieved everything in life already. Multi-millionaire. Beautiful and amazing girlfriend of several years. Big mansions, nice cars, yachts, and jets. Very well respected by my peers. I had it all. I ran out of things to improve about myself. My height was the only thing that was below average. I'd say the benefit of LL was not worth the time and price I paid for it. But I've reached that point where there wasn't really much else for me to do to improve myself.
If any of you guys played MMORPGs, then my life was like I already beat the game already. And now I'm spending months of my life grinding for the last final weapon/armor that improves my character only very slightly. Was it worth it compared to everything else that I achieved and sacrificed? No. There were many other easier to achieve things in my life that causes significant improvements to my overall happiness. Wealth was one of them, probably the biggest one. Getting fit from working out was another. Improving my personality so I'd be more friendly and considerate to others was another.
When it comes to height, I'd say that it's the problem of "the grass is greener on the other side". You THINK that life would be much greater if you were taller. But in reality, it isn't all THAT great. Just slightly better. Now, if it was the matter of whether a tall or superficial girl would date you or not, then it matters significantly. But tall or superficial girl isn't THAT much better than a short girl who doesn't care about your height. From my experience, the ones who aren't superficial tend to be better people for dating.
