I am in my early 20s too so can't provide the depth you're probably looking for but here is what I know so far:

Move to a country/location/environment where you can actually achieve your goals/dreams ASAP. Location is the number 1 determining factor imo. This is step zero, nothing happens without this.

Build a lean, aesthetic physique (assuming you're a guy). Workout and stay healthy.

Get skills ASAP. Stack as many real tangible skills as you can. Skills will pay your bills and will be the foundation of your career.
