Help!!!

Hello everyone, I am a newbie and am in dire need of help as I'm eager to learn but I have little or no experience on how to navigate through the forum.
I joined the forum late 2022 but most of my discussions are being moved to off topics, probably because my discussions aren't of good qualities.
One of the reasons why I got depressed and left but I am back now, in good health and sane mind, ready to learn to improve the quality, and also give back positive impact to the community.

Please kindly recommend me books and guide on how to be better.
Thanks in advance
