Using Auto Correct on the Mac

Hello,I have been having trouble with auto-correct on my Macbook Aire. I have High Sierra. When I was in Pages, I would type a word, auto-correct would want to suggest another word, I would be typing too fast to do something about it and I have to go back later and correct the auto-correct. Does anyone have any suggestions? I would rather not have to turn off auto-correct, as I found it useful in the past. Thanks for any suggestions.
