I’ve come to believe that this is a universal principle: disbelief regarding feasibility prevents actualization of vision; once one sees that it is done it is as if a mental barrier has been removed.
However, even after the mental barrier is removed - Majority of us do not have the motivation to actualize our visions even after we know and believe that they are feasible.
I suspect that it takes a special human emotional/energy makeup to overcome enormous obstacles in pursuit of actualizing a vision. Thats what makes entrepreneurs/hustlers special.

Much of the time the decision not to pursue the vision is the right one, because so much sacrifice is required. A lot of successful entrepreneurs have tragic personal lives because in the pursuit of their vision they sacrifice their families. For those of us who are perhaps older, with a lot of personal commitments, and perhaps are also economically comfortable, those sacrifices are too great.
IMO this needlessly aggrandizes entrepreneurs. The way I see it, certain people end up in situations where they can take the risk, and some take the risk. For instance if you already have some wealth saved up you can take a couple of years to try your idea. Or if you work in a field where you are very likely to be able to get back in. On the other side, you might have relationships that are likely to come with you on your journey, whether that's customers or collaborators.
It just comes down to being able to give it a try, mainly from having a combination of low failure cost and high success probability.
