There is an immediate gratification that you get when a patient comes to you with a very complex brain tumor, and you can go and you can remove that brain tumor successfully, restore function in that patient, and have them go home in two or three days. I mean, you have given that patient and their family something, and that makes you feel good. And again, I may allow myself to enjoy that for a few minutes, but then you realize you have four other patients. You need to go and do exactly the same thing for the next day. So you never allow yourself to become cocky or conceited — “Look how great I am!” — but that’s sort of an immediate gratification. There is a different gratification that comes in research and science, and it’s longer term. It’s the thrill of the discovery. “Wow! We figured out how this works, now that we have been working on it for five years,” and that’s it. That’s how it comes together. That feeling can last for a longer time. It takes a longer time to get to, but you can feel good about that for six months or a year, because the discoveries are longer in between. So those are really sort of the two drives. And then if you can convert that discovery towards a better treatment for your patients… for example, we’re now working on developing what we call a “vaccine for brain cancer” that we’ve taken into clinical trial, and translating that for better care for patients with a disease that we do not have a cure for at this time.
