There is a different kind of feeling of accomplishment when you become a member of an organization by invitation. Especially when that invitation is due to your GPA for a science related major at the age of 34, when aside from a GED the highest grade completed was 8th. It is an organization that breeds success and pride in people of all ages, because it was earned alone, based strictly on hard work and dedication to be a better person for yourself, your family and humanity.
