Luck is what happens when preparation meets opportunity. Perseverance will prevail where all others will fail. It is never too late to be what you might have been. It is impossible to make anything foolproof because fools are so ingenious. Whenever you set out to do something, something else must be done first.
Every solution breeds new problems.
Two wrongs are only the beginning. Those who follow the crowd are quickly lost in it. Nothing in life is to be feared. It is only to be understood. Success always occurs in private, and failure in full view.
