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

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 just a regular guy. I want people to realize that I embody the true American dream. I work hard. I went to school.

I hear hate. I hear people who clearly don't have a great understanding of the American dream. That the American dream is based on hard work and dedication, determination, resilience, excitement, mentorship, help and love for each other.

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.

Doesn't matter how menial may be the job that you're doing today. If you have dreams, that will turn into something positive in the future.

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.
