Impossible? Possibly not...

At earlier points in time, I have touched upon the fact that most of the time life is a matter of prioritisation, and I found it stated in a rather interesting way recently - the words are supposedly those of Muhammad Ali:

Impossible is not a fact. It's an opinion.

Because actually, that's the way things are.
In very few cases we are working with impossibilities - and then we are usually in a mathematical-physical context like perpetual motion, trisecting the angle or squaring the circle.
In the vast majority of situations, when talking about the impossible, instead, it is a question of priority - it may be possible, but it is so complicated or costly that we prioritize not to try to do it.
But still, in most cases, we have a choice - and when something is rejected as impossible, it is simply because it is decided (by more or less conscious decision) that it should not be prioritised.
That something is impossible is thus reduced to anyone's opinion - not a fact.
