I often hear that not everyone is capable of getting a PhD, but then again if we take the same energy and dedication of a career and push it over into education I think plenty have the capability. I often consider myself exhibit A so to speak since I got my GED and was working three low end jobs (line cook, gas station attendant and construction worker) until I bounced out of the workforce and pursued my PhD in Public Policy. I'm sort of playing around with undergrad level math now as I prepare for a second PhD. Seriously think if I could manage at least one PhD anyone else could easily manage 2 or 3.
