FORMS - Initiate vs Activate Whats the difference?

If I am putting code into a userform (to formate some texboxes) whats the difference between Initialize and Activate???

Use Initialize, when the Form is commited to Memory. Activate simply means it's the Active Window, avoid the latter.

I'm a chubby, old retired guy trying to learn some programming in VBA. I have no clue what was said here (above). I know it's oversimplified but is it ok to say, "Don't use Activate. Do use Initialize"? Or, it's better to use "Initialize"?
