I'm a male in Texas, former LEO/corrections employee, licensed to carry concealed (and open, come Jan 1) which I do 24/7 if I'm not at work. When at work, I keep it in my car and immediately place it inside my waistband in a holster when I get in the car.
In Texas, employers and private businesses can prohibit concealed carrying on their premises, but they must do it with signage with very specific verbiage (known as 30.06 signs and 51% signs) easily viewable by anyone entering the premises. My hospital has 30.06 signs posted, so it is indeed illegal to carry there.
A lot of restaurants and stores print signs they find on the internet, and hang them. Those signs are not legally binding, and most CCL holders walk right past them with their concealed firearm. I do, but sometimes I'll make an effort to educate the manager before I leave. If I'm carrying (and I always am) and come to a store/restaurant with legal signage banning the firearm, I leave and go elsewhere. I do not just go back to the car to disarm and then go back inside that business.
My wife is also licensed. I started taking her to the range, introduced her to shooting around the new year because she travels for work frequently, and I want her able to defend herself in hotels, parking lots, etc when I'm not there. She LOVES shooting, and we go to the range practically every week for a couple of hours. She's quite good at it, too.
