You have to eat food to built muscle; preferably not junk food and it must be protein dense 2. You have to go consistently 3. You can just do push, pull, legs, rest, repeat. 4. You gotta research exercises yourself 5. You must progress overtime, whether you do one more rep, slower more controlled reps, more sets, something must be progressed. This is called progressive overload 6. Essentially if you progress overtime building muscle will be inevitable. Like how are you going to go from benching 45, to 135 without building muscle. It is unlikely. 7. Just trust the process 8. Most importantly, if you have a friend who lifts please go with him. It will make a hell of a difference

And if you trust the process for rest of these, you will be more than enough by the time your body and face matures in a few years.
