How do I proceed to seriously study Buddhism?

I have been sincerely studying Buddhism for the last 6-8 months. - I have covered most of the famous authors and teachers namely **Ajahn Brahm, Thich Nhat Hanh, Bhikkhu Bodhi, Tenzin Palmo, Alan Watts, D.T. Suzuki, Sharnyu Suzuki.** - I watched a few **youtube videos of Ajahn Brahm** to get some idea of Buddhist outlook towards life. - I read most of the books available out there to cover the history of the Buddha written for the beginners. But I am ***not*** much interested in the history, specifically the progress of sangha and spread of Buddhism in East. - I have read a few topics that interest me on this stack. - I completed 2 10 days Vipassana retreat and one-month long Zen retreat which included a mini shesshin. But now as I see the amount of literature is simply enormous. The Tripitaka, itself is massive. For an e.g., I tried reading an article on 12 nidanas on the wiki but it's difficult to read it that ways. It just feels like information overload. Can you guide me how should I proceed from here studying **Theravada, Mahayana, and Vajrayana**? Give an answer based on the school you are following. In your answer also include the source from where to study, for e.g. '*Read about 8 fold path from this website*'. Please answer in the following format: **Theravada** Study in following order. 1. 4 Noble Truth 2. 8 fold path 3. 10 paramis Also kindly include the recommended retreat and study centers world over that you know of. Imagine that I will be studying this dedicatedly for the next 3 years or so. Also, include the online resources and paper books if required.
