I never believed I would reach 100 WPM using touch-typing when I first started using this website. But now I am doing just that, and all it took was just a little bit of patience and monitoring of my growth. So why can't little Billy do it too? The "appeal to death" logical fallacy at the end is just the icing on this negativity-inducing pile of crap, too... Haha.
Look, you may not walk on the moon in the near future, and the dream may never materialize in your lifetime, but that doesn't mean your passion for astronomy is a lie now, is it? And if you've got the passion and the commitment, who's to say it won't be the catalysts that will make those supposedly delusions a reality, someday?
But I'm being silly of course. Don't set your mind in pushing your limits in sports, academics, arts and everything else you do, bro! Because someday, we're all going to diiieeee brooooo!
