Climbing to the top demands strength, whether it is to the top of Mount Everest or to the top of your career.
Never let the future disturb you. You will meet it, if you have to, with the same weapons of reason which today arm you against the present.
You have power over your mind - not outside events. Realize this, and you will find strength.
When all is said and done, more is said than done.

I seldom end up where I wanted to go, but almost always end up where I need to be.
It's all to do with the training: you can do a lot if you're properly trained.

Be happy, but never satisfied.
Do not be afraid. Do not be satisfied with mediocrity. Put out into the deep and let down your nets for a catch.
Things may come to those who wait but only the things left by those who hustle.
You have to make the rules, not follow them.
Be yourself; everyone else is already taken.
