Complaint After Complaint

I know that it’s one of the most common mistakes made in the English language, but it doesn’t mean that it should not matter. I don’t know how this all got started. It’s not like the correct answer is poly-syllabic and takes you exponentially longer to say than the incorrect way.
Let me break it down for you. Superman does good. You don’t. Unless you are bolting down the street chasing after a man who just stole and old lady’s purse and a friend stops you in the process to ask what in the hell you are doing, you can’t reply with, “I am doing good!” If someone asks “How was the pizza?” You say, “It was good.” “How did you do on your test?” “I think I did well.”
To be specific, good is an adjective. For those who forgot, an adjective describes a noun: black dog, red hair, etc…
Well is an adverb. Adverbs describe verbs: He ran quickly. She silently left the theater.
Practice and condition yourself into use the right one. Use a mirror. Do situationals with a friend. Anything to help you say ‘NO’ to bad grammar.
