Opportunity arises when a seemingly impossible task is met with an improbable solution.

The impossible often has a kind of integrity to it which the merely improbable lacks. How often have you been presented with an apparently rational explanation of something that works in all respects other than one, which is just that it is hopelessly improbable? Your instinct is to say, 'Yes, but he or she simply wouldn't do that.

Sometimes the best solution is to stop trying to change people.

When you have eliminated the impossible, whatever remains, however improbable, must be the truth.

Opportunity may come to the patient, but always comes to the persistent.

Often doors of opportunity are opened, but few opt to walk through them.
