Have you considered eat protein and picking up heavy things so you're muscular short and hairy? Personally I like my short hairy body more when I'm eating good and lifting.

You failed in one or more >lifting enough >eating enough >sleeping enough
If you eat at least 100g of protein a day, push yourself in your workouts, and get at least 7 hours of sleep there is no reason besides genetic defect or fucking tapeworm o algo that you don't gain muscle.
It ackshually gets harder to get a nice muscular body the taller you get.
