Is a new week like a new life?

Is a new week like a new life?

Everyone is so exited for a new week and thinks that since it's a new week they can do more and new things they couldn't before. It's like they think they will get a new life or something this week. I might just sound negative.  

But why do people act like this?

You can do whatever you want, whenever you want!

As a perfect meme once said "Just do it!"

All I know is that for me, a new week is nothing special.

What do you guys think? How to you act when it's a new week?
