GREAT choice. Your story is like mine...high school baseball. One difference is that you are quitting at the age I told myself I would quit...but then I kept dipping for another 9 years!!!
Actually, my deadline(s) were college, grad school, first job, new car, new house, birth of son...then daughter....it is embarrassing how nic compromised all of my personal goals and deadlines.
But no more...I'm 24 days quit after 20 years. You can do it, too. Embrace the suck, post up, repeat, and stay glued to this site. This site is the only thing that has kept me from caving. YOU CAN DO IT.
