First u have to feel like u are tall that is the starting point to get taller "believe that u are tall as ur dream or as u wann it" then let it go the proccess....and u will not see difference in ur hieght with one month it will take one or two year to see big difference so u have to be patient boy u are still teenage so u will grow more but dont get frustrated about ur height bc u will not grow if u care more about ur hieght.....i worked out stretching exercise for 3 month and 2 week and i grow 2 cm so be patient
