I believe that truly memorable quotes are those that sum up the experiences, observations of life. It is amazing to read, notice the difference and yet agree with all the quotes made about the same aspect by various authors..
Let me start my list with a quote from my favourite cartoon strip Calvin and Hobbes.
Sometimes I think the surest sign that intelligent life exists elsewhere in the universe is that none of it has tried to contact us.
Bill Watterson, cartoonist, "Calvin and Hobbes"
It is not incumbent on us to succeed, but neither are we free to refrain from the struggle.
Rabbi Tarfon
Life is merely a fraction of a second. An infinitely small amount of time to fulfill our desires, our dreams, our passions.
Paul Gauguin, Postimpressionist Painter
Of all the tyrannies that affect mankind, tyranny in religion is the worst; every other species of tyranny is limited to the world we live in;
but this attempts to stride beyond the grave, and seeks to pursue us into eternity.
Thomas Paine, World Citizen and Democrat
Men learn to love the person that they are attracted to and the women become more and more attracted to the person that they love.
Movie, "Sex, Lies and Videotape"
If something was wrong, I told them what was right and left it to them.
Frank Worrell, West Indies Cricketer
