Yes, our handicaps, perceived or otherwise, make things harder for us but they also make things interesting and give us something to work with. You are a certain height. My stepson is 226cm, can't do/be any of the things you complain about not being able to do/be but has constant intrusive questions about his height thrown in by strangers everywhere. His wife has to enter into some stores with double doors first and tell him when it's okay to straighten up? He has to bend, look at the ground to get in.
Who YOU are is not dependent on what you look like. You get to decide who to be, what you will do. If you want to chase after situations where your height would make things difficult for you and not helpful to me (army, police, etc.) you can choose to spend your time banging your head on that wall but why? You're like the rabbit trying to climb a tree in a contest against squirrels.
American football loves short running backs because all the other guys are taller and have a harder time getting "down" there to tackle someone that size, assuming they can see/track the guy coming with everyone around him being taller so they block the view. Too, closer to the ground as they are, they're harder to knock off their feet, their center of balance is better/lower.
A lot of lovely women are your size; think about that for a moment. You're the "right" size for them! No woman likes feeling overpowered and looked down upon! I stand on a step so that my husband and I fit well together in one another's arms. Otherwise I have to talk to his chest
Sitting in a chair and working on a computer, no one knows/cares how tall you are or aren't? If you can answer another person's questions, solve a problem for them, your height is the last thing on their minds! My stepson uses his height (and bright red hair) to remind people they "won't forget him" nor will he forget them (when he was a store manager and had a difficult customer or thief and told them not to come back in the store anymore :-) It makes a wonderful selling point. Think of how other guys might misjudge you because of your size and you might be able to outsmart them since size doesn't have anything to do with smarts.
