That's a better reason. I was in the same position as you. Everything else in my life is above average except for my height. It was like a stain on clean bed sheet. But I can't imagine feeling that way at 180 cm. Wow. You put some really high standards for yourself. No judgement from me, though, since I put high standards for myself as well.
But do you ever wonder if your situation is like this: When I was younger, I wish I had a million dollars. I said that if I had a million dollars, I'd be happy with my life and never think about money again. Fast forward to when I made my first million dollars. I buy a house and suddenly I'm back to having no money left. Now I say to myself, if only I had $10 million, I'd be happy with my life and never think about money again. Fast forward to when I made $10 million. Now I can afford almost whatever I want. But I still want more. Now I wish I had $100 million and I wish I were taller. But after this surgery and going through all of this pain and wasted time, I realized one thing: I'm never going to be fully satisfied if I just keep moving the goal line further away. I wish I were back to being poor again and being just happy with $1 million. Now if I make a $1 million, I don't really feel the same type of happiness that I first felt.
I mean, yes, I want to get taller and be richer. But after actually going through with the surgery, I rather have an extra half year of my life back than to go through another surgery. It's not just a half year of your last years, where you won't be doing much anyway. It's a half year of your limited prime years, where you could be doing so many young people stuff. Young people stuff that require working legs. For example, I used to play sports a lot and go snowboarding. I can't imagine doing that kind of stuff for years. I can probably do it after a year, but I wouldn't be as good as I used to be. And I probably will not enjoy it as much because I'm not as good as I used to be.
This surgery was positive for me in a different way besides fixing my height neurosis. It made me not take my athletic legs for granted. It made me not take my youth for granted. It made me not take my time for granted. If you want to simulate what it's like, then try not doing any athletic stuff or jumping or working out or sports or certain sex positions (almost anything requiring use of your legs) for half a year. See if you think it's worth it to not be able to do all those things.
