If you really are 6ft and really are considering this (assuming you're not a troll), I'm horrified. Even in your country, there is absolutely NOTHING wrong with being 6ft. You are at the very least on a level playing field, and your height shouldn't even be on your mind.
Hell, I'm just below 5'6" and I've had trouble deciding to go through with this (I'm now 99% sure that I am, though). Since I was a teenager, I've always felt that, at around 5'8", if you have other things going for you (which I most certainly do), you will be just fine. Below 5'8" is when you really start to run into problems. I'm looking go from 166.5 cm to 173.5-174cm. At that height, which is still short, my other positives (good career, education, facial aesthetics, etc) will compensate.
I get so angry when men who are already 5'10"+ think they're "short." You may not be TALL, but assuming you have other things going for you (education, looks, decent body, etc), there's no reason you can't succeed in all areas of life.
But if it makes you feel better - go for it.
