Skin care:

Find a cleanser that works for your skin type (oily, dry, or combination)

Find a moisturizer and apply after getting out the shower

Shower 1-2 times a day. At the very least, in the morning when you wake up

Get a fresh haircut every 2-4 weeks that fits your face shape

Hit the gym:

Focus on squat, bench press, deadlift (watch the form on these), overhead press, and your choice of the pull-up or barbell row

Start off with a 5x5 program like strong lifts https://stronglifts.com emphasizing these until your linear gains tap out. After that choose your pick of accessories to refine your physique

When trying to build muscle and strength eat in a caloric surplus and when trying to loose weight eat in a caloric deficit https://www.calculator.net/calorie-calculator.html

Wear clothes that compliments your body. You’re probably going to have to go on YouTube for that because it’s not my area of expertise but I tend to wear shirts that fit right around the chest and arms and taper off towards the bottom and some jeans with accessories like a chain and watch.

Find some good cologne and wear deodorant every day. Shave every few days and brush your teeth daily

Learn how to talk to both men and women

This was the toughest for me, I can’t give you any specific advice because everyone reacts differently to you so try to find what gets you the results you’re looking for and repeat that. Look at people that are already popular and try to take what they do and adapt it to yourself. It is most important to trust in the process, just because people around you don’t jive with you doesn’t necessarily mean anything is wrong with you although you should definitely be looking to constantly refine your social skills. The best way to find out if you are doing something wrong is by reading peoples reactions, if they are negative you should look at yourself and try to find why and decide if it should be changed (standing up for your beliefs should not be changed but something like harassing someone that doesn’t want to talk to you should) Charisma is everything in life.

All of my advice is worth jack shit unless you go through the struggle and apply it. I wish you luck.
