Xkcd has recurring characters and storyline that are separated but connected. Blackhat is basically an asshole with style character (a classhole). The girl is Danish, the only person to one up him, and them meeting and their relationship is in the "Journal" series.
A few others are white hat, who isn't always the same person, as well as Cueball, Mrs Roberts (mother of Lil Bobby tables) and a few others. You don't need tro know them to get a comics joke, but if you follow the whole work it's like little Easter eggs you can find.
In context it's not so bad but it's really stuck with me as particularly self descriptive the past decade or so as I keep hurting myself by allowing myself to hope over and over again
A cycle of mediocrity is not an identity or intrinsic trait ffs. That's wrong on several levels.
First of all, expectations. We can't all be Nobel prize winners or cure cancer or whatever else qualifies as excelling.
And also, if you're not happy now, chances are achieving great things won't do it for you either. Usually the people that society ascribes greatness to sacrifice many important things and often are giant assholes (see Steve Jobs as just one example of many).
Plenty of average people are actually happy without being the supposed top of the heap.
But if you're failing to achieve your dreams -- or failing to even try to in the first place -- it may be due to myriad things one can indeed work on. E.g., it may well be related to a mix of some past trauma, depression, ADHD, or expectations, values, lack of knowledge or skills.
Assuming you have realistic goals, the only way to guarantee you'll never achieve them is to give up.
