Honestly, "stop having fun" was the single best decision I have ever taken. I began studying a lot, I started to actually code my small personal projects, I began working on fiverr (I'm indeed still a student) and I'm much more confident in myself now.

Ironically, when I was hiking 15 days without internet and coudn't sleep at night, I began scribbling down a similar essay: points 1 and 2 are the same, stop having fun and experience true boredom. I'm very glad someone got my same idea.
