Mm. Indeed. It takes some amount of willingness to push through for a better result to make it against adversity I believe. Simply expecting things to work out without thinking that you must contribute to seeing that they do is... a mindset. But not one that will see one very far, in general.

But the self-determination to believe things can improve is a point most people here have to some degree, if only from necessity. The other option is to embrace nihilism, and while that works for some, most would rather cling to some hope of their actions mattering.
