Question about where to start

Hello! I have some knowledge on OSINT, but recently i’ve been taking an interest and wanted to know where i should start learning. I know basic search operators, sites like thatsthem etc. but that’s about the extent of my knowledge. I did however find a site called freeosint.org (redirects to a github page) and they have a bunch of different modules with what seems like decent information on starting. If you have any other tips besides using that I would really appreciate it. Thank you so much in advance for any help you might give!!
