An optimist is a fellow who believes a housefly is looking for a way to get out.
The future has many names: For the weak, it means the unattainable. For the fearful, it means the unknown. For the courageous, it means opportunity.
Even if I knew that tomorrow the world would go to pieces, I would still plant my apple tree.
The ship of my life may or may not be sailing on calm and amiable seas. The challenging days of my existence may or may not be bright and promising. Stormy or sunny days, glorious or lonely nights, I maintain an attitude of gratitude. If I insist on being pessimistic, there is always tomorrow. Today I am blessed.
When you're still too young to shave, optimism is a perfectly legitimate response to failure.
The place where optimism flourishes most is the lunatic asylum.
I love the man that can smile in trouble, that can gather strength from distress, and grow brave by reflection.
A positive attitude may not solve all your problems, but it will annoy enough people to make it worth the effort.
The basis of optimism is sheer terror.
