What do you do if you mix up your tenses in a sentence

There are many ways to go about this. The common tense rule is this: The tenses of verbs in a sentence must be consistent when the actions happen at the same time. When dealing with actions that occur at different points in time, however, we can – and probably should – use multiple tenses in the same sentence.

Hope this helps!!
