The primary topic here is Intellectual Development and Wisdom and YouTube is an amazing Resource and Reference Resource, a true treasure, where you can find information of an almost infinite array of topics, learn how to resolve problems you are confronted with, gain inspiration, and so forth.  YouTube is not perfect but it is so good that its merits far outweigh its flaws.  

Contributors have vast complaints about monetization, excessive censorship, and many other problems.  Many times they will have channels on YouTube but guide users to their private websites for uncensored material where they have the option of being Patron and get the exact information that they are willing to pay for.  But for the general public one can pick their favorite subject and get up to date information or use it for any other objective you may have.

I am going to provide sub pages in the drop down menu that for topics that I think are important. But clicking on the YouTube icon in the right column will take you to the YouTube website where you can pick you own topics.
