Congratulations. Here are a couple of things that I recommend for armed citizens to remember.
1. Have your gun with you at all times. The unexpected is self defining.
2. You are not a police officer and should ever act like one.
3. Spend time thinking about how to avoid dangerous situations.
4. Practice, practice, practice.
5. If you can't articulate the grave danger, a shooting will be hard to prove self defense.
Lastly, this is a personal decision and not intended to be critical of anyone else's decision. I carry two things concealed. The first is my license, the second is my gun. What I mean to say is the less than 5 people on earth know that I have a license and that I ALWAYS have a gun on me where it is legal to carry.
Another thing to consider: this undoubtedly change your entire mindset (as it should). I have found that since I started carrying, I no longer get upset dealing with traffic. Just knowing the awesome responsibility involved in carrying a deadly weapon seems to produce a calming effect, and "don't sweat the small crap" comes into play more often than the previously normal "WHY YOU STUPID [email protected]&@&$$*)!!!".
Note that if this phenomenon doesn't happen to you, you should probably leave the gun at home until it does...
