For me, any book is a source that carries certain knowledge and valuable information. And it's a pity that there is not always time for this. Due to the irrational use of time and the habit of putting off everything to the latter, I often accumulate a lot of tasks. Cope with which on my own is simply not realistic. Therefore, in such cases, I use examples and it helps me a lot. I always get ideas and inspiration here. It allows me to complete all my tasks on time and even get good grades.
