I don’t think a life without deadlines would be good. As much as we tend to dread deadlines, they are important to keep us motivated. A life without deadlines is a life without much productivity. I am self-employed and like to impose deadlines on myself in the things that I do, because it helps me be productive. For example, I tell myself I’m going to write one article per week. That way, I can actually write that article. Otherwise I will write very slowly and not get much done.
With that being said, I generally prefer a slow-paced lifestyle. My flow is different from everyone else’s. I even shifted my weekend to be able to go out when public places are not busy.
