You have to have passion for everything you do, and you've got to look at the positive side.

If you look at some of the clips of me in the operating room, I sit in the chair, I control the microscope with my mouth, I connect, my hands are always working in the brain, my feet are controlling everything.

The same skills that I used as a welder, as a migrant farm worker, are similar skills that I'm using as a brain surgeon.

I'm not a genius. I just worked really, really hard, and I want our generation, our children and our future generations to realize that they can fulfill the same dreams.

Developed countries will always welcome the Einsteins of this world - those individuals whose talents are already recognized and deemed to have value. This welcome doesn't usually extend to the poor and uneducated people seeking to enter the country. But the truth, supported by the facts of history and the richness of immigrant contribution to America's distinction in the world, is that the most entrepreneurial, innovative, motivated citizen is the one who has been given an opportunity and wants to repay the debt.

The greatest gratification that I get to work with these hands is that when I come out and I go to the waiting room and speak and talk to the families of my patients, I get standing ovations and I get tears and they look at me as superhuman and superhero. No amount of money, no amount of anything can ever compare to that feeling.

You know how in sports baseball players, they hit home runs. Football players, they throw and they score touchdowns. I get to do something that very few people get to do - I get to touch the human brain, and every day I get to hit home runs, I get to score touchdowns.
