Starting a Bar

I have decided that I would like to start and run a bar. I love the atmosphere of a calm bar and love running a business. I bought a book about it and am about 1/5 of the way through. I won't be starting it anytime soon, just trying to get all the info I can so I can decide if I can do it, and what steps I need to take in my life to go in that direction. Maybe a bar in Texas? Who knows?
