ELI5: Why do we get the motivation to change our lives around late at night, but it's gone the next morning?

For example, start working out, eating healthier, studying more..

Edit: Thanks for all the answers!

Because when you're in your bed at night you know you won't start doing those things right there. So it's easy to start big plans and feel like you can change your life, because you don't have the obligation to actually do it. It gives you that confidence that everything is possible. But when you wake up in the morning and have the possibility of actually doing it it's less motivating because you have to actually move your butt and do it.
