Learner Trip

PhD in Education. I've been sharing all kind of content/information on the Internet for 14+ years now. I try to do it in the most straightforward and reliable way possible, cross-referencing information with the primary sources of authority in each field (unless unnecessary). You can reach out to me in the comments. I read all your inquiries and typically respond to most of them daily. If you find what I do helpful, you can support me here. 🙂
