If you still desire to serve, I echo what the others have said, which is to first select a job (or a short list of jobs) that interest you. The different branches have different specialities. When selecting jobs, I encourage you to consider a career which also has a civilian equivalent (i.e finance, medical, public relations, logistics, etc.). Careers without a civilian equivalent, like infantry, artillery, munitions, etc., can be very confusing to civilian employers, and may make it difficult for you to get a job after your military service ends.
I won't tell you to solely consider jobs though, because the overall culture and standard of living is also an important consideration, and there is a lot of truth in the military branch stereotypes. If you want me to explain those stereotypes in greater detail, I will.
