> Why not? The future can be anything.

I don’t think the ability to come up with an implausible scenario where a person could become the thing that seems impossible is the same thing as saying “if you have enough motivation, you can become anything you want”. Both scenarios you described require a lot of things to happen that you are not in control of; space flight changing significantly and colonizing mars aren’t something you can work at.

Also, the height limit isn’t just a made up rule, it is so you can fit in the spaceship.

For the wheelchair basketball player, they can’t just work hard and suddenly the NBA lets people on with bionic legs. That would require a major rule shift, which again is not something you can change through hard work and motivation.

Look, I get why we want to persist the myth that you can accomplish anything though hard work. You CAN accomplish a lot, and probably more than you think, through dedication and hard work, but you definitely can’t if you don’t believe you can. So, we tell ourselves (and others) that you can be anything if you work hard so as to encourage people to try for things they might not try for because they don’t realize they can accomplish the thing if they work hard. It makes some sense to try to delude yourself into thinking you can do anything in order to prevent the situation where you actually could have accomplished the thing you wanted to do, but you didn’t try because you didn’t think you could.

So I get it, but really, if you think it through… there are things out of your control that will factor into whether you can accomplish your goal or not, and you have to be prepared for that, too.

We're kinda talking about different philosophies here. There's "can it be done in any timeline" and "can it be done practically". Of course it can't be done practically. But if that is a 100%-filter on the things you attempt, then things that aren't likely to ever happen will never be attempted. Things go a lot better when people have unrealistic expectations and then end up in places they didn't expect (probably not the place they aimed for...). That's a moral worth nurturing, even if it is not any sort of practical approach that you would stake anything on.

Basically: it is false that you can be anything in particular if you work hard enough. But it is true that the best way to act is as if that were true to some degree, because the outcomes are better for everybody.

It sounds like we are actually in agreement, then. You can absolutely achieve more things than seem possible, but you can’t achieve everything. I don’t think it is a bad idea to try things that seem unlikely to succeed, or to believe you can achieve something that is rationally very unlikely. You are right, having some irrational belief in yourself will often lead to more positive outcomes.

I just think you shouldn’t conclude that you just didn’t work hard enough if you don’t achieve every dream. As Captain Picard put it, “It is possible to commit no mistakes and still lose. That is not a weakness, that is life."
