Famous quotes containing the word companion:

    Ambition is an uncomfortable companion many times. He creates a discontent with present surroundings and achievements; he is never satisfied but always pressing forward to better things in the future. Restless, energetic, purposeful, it is ambition that makes of the creature a real man.
    Lyndon Baines Johnson (1908–1973)
