Take showers everyday. Because of puberty, your sweat glands are becoming more active, which are creating different chemicals that cause sweat to turn into a disgusting odor. So, to make sure you're getting rid of all this smelly odor you should use a mild soap and warm water! Even if it's hot outside you need to shower in warm water, because that opens up your pores which means you get to clean more of that smell off you. Then rinse off in cold water to shut your pores and eliminate the amount of bacteria that makes you stink. Wear clean clothing and apply deodorant to your now clean armpits and that means changing your socks and underwear every day. Brush your teeth at minimum two times a day. Strive to try and brush your teeth after every meal!

Be positive in all the things you do.

Hi... Work hard and be strong!

Im so happy for you ! ... but wait... it depends on what "healthy growing life" means to you. If you are determined, INVESTIGATE all about it and then DO IT under your own terms ! =D

Eat healthy try not to eat to much junk food, do not drink or smoke, exercise at least 3 or 4 times a week for about 30min. Try to get your 8hrs of sleep and that is the end of my suggestions. Hope I helped you in anyway.
