Self Portrait vs the Selfie

What is a selfie?

A selfie is a picture that you take by yourself on your phone or camera. you get to express more when taking selfies and exaggerate your emotions more because you can respond on your own rather than a professional taking the pictures and them telling you what to do or what would look good.
What is a self portrait?

A self portrait is i feel something more serious. You have to focus on what would look good and lighting and background. I feel that you have to plan more with self portraits rather than selfies you can just snap a quick picture and have fun.
Is there a difference? If so, what?

There is a difference. You don't always need a professional but you can for self portraits. You take more time with them and you take so many to get the right one. I feel like they can be the same too though because you can spend a lot of time getting the right selfie.
What style do you prefer?

I like selfies because you can express yourself more and they are fun to take. Also you can take really funny and stupid pointless pictures.
Is one more valuable/important than the other? Why?

I don't think one of them i more valuable. It depends on the person and what the person likes.
