Champions behave like champions before they are champions

Machines aren't replacing proofreaders at all. Copy editors, who proofread and much, much more, use spellcheck as a tool but read every word that appears in the paper

If your why is strong enough you will figure out how!

My theory is that, just like with omitting a final comma in a list when not essential for meaning, publishers are trying to save paper and ink or pixels on-screen.

On occasion I omit commas. On occasion, I use them. (The more you know about English, the less you're likely to think there are unbreakable "rules" for a lot of these things.)

I caution against beginning or ending a quotation with ellipses

Concentrate on what will produce results rather than on the results, the process rather than the prize.
