Here is a list of things that you will learn as you carry more.
You will learn not everyone can see the outline of your gun and not every movement flashes it.
You will learn not everyone is pointing at you - "He's got a gun!"
You will learn that the more you wear it, the more comfortable you will be with it. If you have a truly GOOD holster/belt combo, you will hardly notice it.
You will learn to "dress around the gun". Dark colors and patterns are your friend, as are loose-fitting shirts.
You will learn to not tug on the hem of your shirt every 5 minutes to assure yourself you're still concealed.
You will learn to stop constantly adjusting the holster. In fact, if the holster/belt is the proper fit, you won't need to.
You will learn to stop touching the butt with your elbow just to assure yourself that it's still in place.
You will learn to give a little extra clearance on your carry side.
You will learn to reach overhead with your weak-side hand.
You will learn to stoop or kneel rather than bend.
You will learn to move through crowds with your strong side to the rear.
You will learn to embrace low, to force your counterpart's arms/hands up, away from your piece.
