Good for you. Now wear it to Wal-Mart and buy ammo. It is an empowering feeling!
Carrying will feel very strange at first as you will think everyone around you is going to see it, or that they "know" you are packing. You'll grab at your gun/holster a thousand times worrying about it, and you'll just be on edge a little more than normal. Don't worry, though, as all those things will pass soon enough.
All of them that is except being on edge. I find carrying helps me maintain a much better sense of situational awareness and this is definately a good thing.
