Do you think playing with abstraction is easy? I get up at 6 o'clock every morning to memorize memes, and read Internet hot topics at 8 o'clock. I don't let go of every hot memes until I master the use of all kinds of bad memes. Being abstract, meaningful and comprehensive requires a large amount of knowledge reserves, keen insight and excellent language organization skills. Real abstraction cannot be prepared in advance according to routines. You can only see my abstraction, but you can't see the efforts I put in behind it...
