Do you think it’s good for us to allow ourselves to do whatever we want all the time? Or should we give ourselves personal restrictions??

For example, I should probably go to bed right now but I don’t want to. The last time I should have gone to bed I let myself watch another episode of my favorite show, but this time, although I know I could definitely go for another episode I’m making myself go atleast lay down in the bed with the intention of sleeping instead… Do you think that’s okay? Or should we always do what we Feel not what we Think is right?
