> Abstract thinking is good in the next step, when you already know the topic. I honestly find the abstract perspective much more "approachable" (I really find it quite easy to learn highly abstract mathematics). The issue rather is that very abstract texts have much higher quality demands on the writer - if you explain things badly, the reader will likely not understand. Similarly, much less (subtle) errors in the text are acceptable before the reader will be confused.
