Visit all the units you can. You never know which one will stick. The pilots there will give you all the free advice you can take. Everyone has a different story of how they got there. The main theme of those stories will usually be persistence. Go visit baseops. net and read their UPT advice. Millions of stories there. Realize one thing, however. Once you enlist there is no guarantee that you will become a pilot. You are also their Biatch for the next six years with some caveats.
