The first thing that comes to mind here is the quote "the person that loves walking will walk further than the person that loves the destination". I agree with you there is an inherent expectation in this world to be "great" but I think the real goal is to fall in love with the pursuit of greatness. Try not to slip into the nihilistic mindset of "I will never be great" as greatness can be defined on many different levels. Instead frame it as I am on the journey to becoming great. Ill either be great or die trying to be great
