When Should You Use Too’?

Replacing the words “also”, “including”, “as well as”, etc. "I like writing and editing. I also enjoy proofreading’" can be written as  "I like writing and editing. I enjoy proofreading too."

Signifying something extreme, or a lot "He spends too much time reading research articles." When writing, you have to think of the context before using ‘to’ or ‘too,’ and you’ll never mix the words again!
