> just

In my experience this word means you don't know whatever you're speaking about. "Just" almost always hide a ton of unknown unknowns. After being burned enough times nowadays when I'm going to use it I try to stop and start asking more questions.

It's a trick of human psychology. Asking "why don't you just..." leads to one reaction, when asking "what are the road blocks to completing..." leads to a different but same answer. But thinking "just" is good when you see it as a learning opportunity.

I mean, perhaps, but in this case "just" isn't offering any cover. It is only part of the sentence for alliterative purposes, you could "just" remove it and the meaning remains.
