Believe when I tell you I am the furthest things from a bleeding heart do gooder.
My entire life was just about making money as an engineer so I could retire as soon as possible. I never felt I contributed anything to society that had any real meaning (everything I designed and worked on is/was hidden in a box in a server farm).
One time a few years ago a man and his daughter came into the library at night. The man only spoke very broken English and you could kind of tell they were poor. The man tried to explain to me in his broken English that he did not have computers or internet at home and his daughter needed to do her college applications.
I was able to work with them over a few nights since I had just been through the process myself with my daughter and knew the process intimately and was able to help them through it. I did not see them again until many months later when the man alone came into the library, crying, saying his daughter would be the first in his family to go to college, and then hugged me and left.
That was pretty cool and a moment you don't really get to experience when you are just chasing money for a living.
