“Learning is the only thing the mind never exhausts, never fears, and never regrets.”

“The best thing for being sad," replied Merlin, beginning to puff and blow, "is to learn something. That's the only thing that never fails. You may grow old and trembling in your anatomies, you may lie awake at night listening to the disorder of your veins, you may miss your only love, you may see the world about you devastated by evil lunatics, or know your honour trampled in the sewers of baser minds. There is only one thing for it then — to learn. Learn why the world wags and what wags it. That is the only thing which the mind can never exhaust, never alienate, never be tortured by, never fear or distrust, and never dream of regretting. Learning is the only thing for you. Look what a lot of things there are to learn.”

“Learning never exhausts the mind.”

“The key is to never let anyone tell you that you can't. I'll try just about anything - no fear, no regrets, and never half way. :)”

“Make it a rule of life never to regret and never to look back. Regret is an appalling waste of energy; you can't build on it; it's only good for wallowing in.”

“He took her hand without question, without fear, and he never regretted it.”
