Let me tell you the secret that has led me to my goal. My strength lies solely in my tenacity.

All truths are easy to understand once they are discovered; the point is to discover them.

I am not accustomed to saying anything with certainty after only one or two observations.

Good information is the best medicine.

If you think compliance is expensive, try non-compliance.

I must say, I spend a lot of my time these days trying to persuade people that controlled trials are the only way to get information that’s reliable about drugs.

The cures we want aren’t going to fall from the sky. We have to get ladders and climb up and get them.

Without drugs, physicians would struggle to find relevance, and patients would suffer without hope.

There is so much more to be done; the patients are waiting.

The greatest joy in life is to accomplish. It is the getting, not the having. It is the giving, not the keeping.

It is easy to get a thousand prescriptions, but hard to get one single remedy.

The reward for work well done is the opportunity to do more.

One never notices what has been done; one can only see what remains to be done.

Drugs don’t work in patients who don’t take them.

I trust I may be enabled in the treatment of patients always to act with a single eye to their good.

The pace of discovery is going unbelievably fast.

One sometimes finds what one is not looking for.

Remember the Three Princes of Serendip who went out looking for treasure? They didn’t find what they were looking for, but they kept finding things just as valuable. That’s serendipity, and our business [drugs] is full of it.

Advances in drug development have led to greater improvement in the quality of human life than advances in all other fields combined.

I have no ideology. My ideology is health.

The best way to predict the future is to invent it.
