A thoughtful mind, when it sees a nation’s flag, sees not the flag only, but the nation itself; and whatever may be its symbols, its insignia, he reads chiefly in the flag the government, the principles, the truths, the history which belongs to the nation that sets it forth.
—Henry Ward Beecher (1813-1887)

Never be afraid to try something new. Remember, amateurs built the Ark.
Professionals built the Titanic.
