You will never stub your toe standing still. The faster you go, the more chance there is of stubbing your toe, but the more chance you have of getting somewhere.

Keep on going and the chances are you will stumble on something, perhaps when you are least expecting it. I have never heard of anyone stumbling on something sitting down.

The only difference between a problem and a solution is that people understand the solution.

People are very open-minded about new things - as long as they're exactly like the old ones.

The only time you mustn't fail is the last time you try.
