Mark Twain said this quote

I have had an aversion to good spelling for sixty years and more, merely for the reason that when I was a boy there was not a thing I could do creditably except spell according to the book. It was a poor and mean distinction, and I early learned to disenjoy it. I suppose that this is because the ability to spell correctly is a talent, not an acquirement. There is some dignity about an acquirement, because it is a product of your own labor. It is earned, whereas to be able to do a thing merely by the grace of God, and not by your own effort, transfers the thing to our heavenly home--where possibly it is a matter of pride and satisfaction, but it leaves you naked and bankrupt.
