Problems are the price of progress. Don't bring me anything but trouble. Good news weakens me.

If you're doing something the same way you have been doing it for ten years, the chances are you are doing it wrong.

Every great improvement has come after repeated failures. Virtually nothing comes out right the first time. Failures, repeated failures, are finger posts on the road to achievement. One fails forward toward success.

Failures, repeated failures, are sign-posts on the road to achievement. The only time you don't want to fail is the last time you try something (and it works).

Obsolescence is a factor which says that the new thing I bring you is worth more than the unused value of the old thing.

We have reason not to be afraid of the machine, for there is always constructive change, the enemy of machines, making them change to fit new conditions.

Believe and act as if it were impossible to fail.
