“People get from books the idea that if you have married the right person you may expect to go on being in love forever. As a result, when they find they are not, they think this proves they have made a mistake and are entitled to a change - not realizing that, when they have changed, the glamour will presently go out of the new love just as it went out of the old one… But let the thrills go, let it die away, go on through to the period of death into the great but much more profound and interest of happiness that follow and you will find that you’re living in a world of new thrills all the time. But if you decide to make thrills your regular diet and you try to prolong them artificially it will all get weaker and weaker, fewer and fewer, and you will be a bored disillusioned old man for the rest of your life.”
-C.S. Lewis
