I was interested in being a cop for a while but then I watched Brooklyn's Finest and that idea went out the window. I also wanted to have my own business too and have the opportunity to be my own boss. I saw my self becoming bitter too.
Being a mechanic/ home maintenance guy tickled my funny bone too, but I wanted something more intensive and I could also do those things on my own car/house. I also wanted more people interaction. Loved the hands on aspect though.
Surgery was an interest of mine too, but in any ways, it really becomes your life. I didn't want to go down that road.
Dentistry provides me a happy medium with all those things.
