Xavi is neither awesome nor shit. He is a young, learning manager trying to succeed in this tough job, trying to figure out how to deal with the problems of the current football medium and how to make the club he loves work, even though the situation he and Barcelona both find themselves in is hard to fix. He is 100% Barcelonista and cares for the club far more than other so-called legends. You have to respect that even if you don't agree with his methods and choices.
In short terms, you have to fucking wait and don't look at current Barca as an easy entertainment source, to make life hardships pass on easier. The club is not at your service anymore. Like in the past, a bad day at work, tune in and see Pep Barca toy with the best sides like they're a pub team. It's over. You have to do a bit of toughening up and understand the club is past its best period and back to the nasty groundwork. You have to invest some sort of sacrifice in this club for the foreseeable future. The alternative is to pass on and attach yourself to merrier pastures.
Try to downsize the level of what is worthy of appreciation, to match the current reality. In the past, only winning the CL was seen as instant pleasure gratification, even La Liga wins were underappreciated as casual feats. Now, even seeing Pedri and Gavi progress to becoming top-class players has to be seen as a great success for the next 1-2 years at least. As well as Balde, Araujo, seeing De Jong own the DM position, plenty to draw satisfaction for without being an elite team per se.
