Perception is a tricky master, but we can challenge our assumptions and change our routine hunting our habits, everything that make us complacent, as being challenged is the main way to grow.
But it is something that can be allowed for. We can look at our own habits and flaws, and then do something that helps us overcome, or mitigate. Yet, most think "knowing more" will be enough - without ever looking at how to apply what they know.
And yet, in many cases, people did impossible things just because nobody told them that this is impossible.
The impossible is something I have thought about a bit. A lot of people I believe have misunderstood the Ali quote of "impossible is nothing" taking the meaning as "nothing is impossible". I think what is meant is that "impossible is literally nothing". There is what is possible. Nothing else. When we realise this, we can then act as if anything is possible, without having to worry about the other side, because there is no other side.
If we act according to our values, we get the results according to our values.
If we are to connect quotes, a common sense habit of mine is that you can have everything you need, but not at once. and the connection: you can achieve any dream you dreamed, but for some of your dreams you need to work hard. if you are willing to put up with the work needed even the impossible is possible.
Check Polgar research and how he managed to have not one but three daughters to achieve Grandmaster chess rank and become a genius, to support his theory that genius is created, not born. It is one interesting example of achieving the impossible, that was not replicated again.
