The important thing is not to stop questioning. Curiosity has its own reason for existing. One cannot help but be in awe when he contemplates the mysteries of eternity, of life, of the marvelous structure of reality. It is enough if one tries merely to comprehend a little of this mystery every day. Never lose a holy curiosity.
Curiosity is one of the most powerful forces of nature. It can take you places no one’s ever been, and let you do things no one’s ever done. Will that make you weird? Or different? Who cares if it does? Every single one of us is different. No one on this planet is just like you. Being different is what makes you special. So find what you love. Learn everything you can about it. And share the best parts with anyone who will listen. You never know who you’ll inspire.

You must work in the missionary spirit, with a breadth of charity that raises you far above the petty jealousies of life.
The young doctor should look about early for an avocation, a pastime, that will take him away from patients, pills, and potions . . .

But do not get too deeply absorbed [in your work] to the exclusion of all outside interests. Success in life depends as much upon the [person] as on the physician. Mix with your fellow students, mingle with their sports and their pleasures. … You are to be members of a polite as well as of a liberal profession and the more you see of life outside the narrow circle of your work the better equipped you will be for the struggle.
Children are one’s greatest happiness, but often & often a still greater misery. A man of science ought to have none, — perhaps not a wife; for then there would be nothing in this wide world worth caring for & a man might (whether he would is another question) work away like a Trojan.
