Whoah there! Leave me out of it. You may grab yourself a mission, but I want nothing to do with it. Don't call it "ours". I'm not part of your team.
A mission gives the idea of something important to do. something important to achieve. Well, that is a matter of opinion. What is important for one is unimportant for another.
For me, as long as I am able to live life the way I want, that's all that I want really. There's nothing permanently fixed in my sights. The objective changes according to whim. I guess, to live as if I'm a living artwork.
But in terms of a shared mission? No. There's no shared drum. We see things from our own perspectives. We're not ants. (Even ants may not be ants.)
