I've previously said that one should Learn to keep their goals a secret, the reason being that telling people about your stuff gives your brain the illusion that you've already done the work needed to accomplish said goal, when in fact, you haven't.
That's pretty much accurate, but it leaves out some important points. For starters, why does the brain "think that work has been done"?
I still don't know the exact reason, but I do know that it has something to do with the specificity of the goal achievement process. Once you can see so clearly the path from conception to implementation, your brain gets caught by conflicting thoughts of what to do in the moment, and what to do when the goal has been reached.
It is the helplessness of knowing EXACTLY what needs to be done, but being unable to do it (instantly), that just forces the brain into a vicious cycle that ends with "FUCK IT, I'm going to browse Reddit".
Vision, on the other hand, doesn't suffer from this. There is an infinite deadline to a vision that you want to see materialise. It constantly lives in the future, and therefore can constantly be "looked forward to".
For most creators, who are by nature forward thinkers, this ever-unreachable destination creates the strongest kind of fuel for work that you can possibly get. Align several minds on the same wavelength, and we have a force to be reckoned with.
Of course, most can't be free of goals, and I'm as guilty as anyone else at being overly-obsessed with them. I have however, found that shutting up about them helps.
