It is a short book and can help you a lot. The 2 things that still sticks to me even after reading this masterpiece long time ago is that
1. It gives us concept that nothing is original. Everything we write, or say is modified version of what we steal. So, it is better to steal many things from others than only one thing in particular,
2. The second thing is that , if you are writing something and you don't know the public view towards it, you can post it online to have new ideas and public interests too.
It is a good book , you can give it a try.
