Nobody is saying that. And most of us (at least I think) agree that wishful thinking won't turn a sub-optimal app with no II at this point into a stellar piece either. It's more of an inspiration and aspiration thing. The very original post is more so of an encouragement for a long term positive outlook. And
@HomeSkool did explicitly say to work hard at the end.
Harking back to cooking analogy, maybe scrambled egg isn't the best since it is a quick recipe but if you set aside 3 hours of an afternoon to bake a cheese cake, most of us amateur chefs prefer not to begin with a pessimistic stance. It's not that we won't over-mix the cream cheese or add too much vanilla extract or something. We do, that's why we are amateurs, not Gordon Ramsay or Jamie Oliver. However, if we dwell too much on the mid-process hiccups we will lead to more down the road, like baking for too long and burning the crumb crust, especially if by the 60-mins baking mark your nose can't sense that tangy but caramelly aroma that indicates a good midway checkpoint. Sure we can arrange to bake another one next weekend or something, but it's much better to rebake with a mindset that "I will eventually kick@$$ with this recipe" rather than "nope this whole lot is beyond my skill I've just wasted a grocery trip and $$ on more dairy and eggs." Also, depending on the ingredient add-ons and cake styles, some cakes give out that aroma really late or you can't use that benchmark at all. Yet this does not mean you prematurely assume you've sunk 3 hours of mixing and measuring efforts into oblivion without at least hoping for a decent final product at the end.
I may or may not have written this on an empty stomach.
