My mother really was the strength in our family. She would sort of keep us in line and I admired her very much .

Nothing can replace courage, a resounding motivation and that little bit of luck.

I would like to be remembered for the schools and hospitals and bridges and all the other activities that we did with the Sherpas. Unquestionably, they are the things I feel that were the most worthwhile of everything I was involved in.

Strong motivation is the most important factor in getting you to the top

Good planning is important. I've also regarded a sense of humor as one of the most important things on a big expedition. When you're in a difficult or dangerous situation, or when you're depressed about the chances of success, someone who can make you laugh eases the tension.

I still think have this deep desire for our Himalayan Trust - that we raise the necessary funds, that we do all the things that the Sherpas want us to do, and I would like to see us working together with them on these projects. Even though I'm old and decrepit I still have this strong feeling that I would like to carry these things out if it were still possible.

Many people have been getting too casual about climbing Everest. I forecast a disaster many times.
