What sort of things would we do if we were supernaturally teleported back to our days at secondary school except with all of the knowledge and understanding of the world as well as learned skills that we possess today?
Just to be clear, in this scenario we would once again have the body and physical attributes of our school-aged selves but at the same time our current adult mind and level of life experience.
As for myself, I would do the following:
1. Use my current knowledge of MMA to be the cock of the school
Not to sound like a PAG-like conceited braggart, but my combat skills are quite developed. After my time at secondary school I trained extensively in Brazilian Jiujitsu and No-Gi grappling and then took up MMA, adding freestyle wrestling and Muay Thai to my arsenal. I'm a formidable grappler and have a decent level of striking.
With all of this martial knowledge, I would thoroughly kick the shit out of any bullies and wannabe tough guys that tried to start on me. Back at school (real timeline) I only knew how to swing wildly and use a few basic grappling techniques, but in the hypothetical timeline I'd whoop my opponents with much more sophisticated techniques such as crisp Muay Thai combinations including low-kicks, elbows and knees, double-leg and high-crotch takedowns, armbars and rear-naked chokes, and even elaborate submissions like heel-hooks and twisters!
Twister submission – This is one helluva baddass spine lock!

I'd be fuckin' feared bro, because back then even the worst bullies at my school only knew very basic stuff or maybe some kickboxing at most, nothing like MMA or advanced grappling. I'd be the cock of the school, dudes would wanna be my buddy and girls would love me.
2. Improve my physical training and supplements
I began lifting weights when I was 13. But in the hypothetical timeline, I would have a much more precise knowledge of training methods, nutrition and supplements and would therefore develop an ever better physique. I could even order Anavar from online suppliers. Melanotan wasn't well-known in the early 2000s but maybe I would be able to locate an international supplier and order it to my house. The purpose would be to get jacked and tanned and become a complete teenage sex god!
3. Game girls
Back at school I was socially awkward and suffered from crippling social anxiety and therefore didn't get very far with girls even when they took an interest in me, but with my current adult social skills and understanding of social interaction I would hit on all of the hot girls (those who were tanned or brown and had good titties and ass) and bang many of them. I'd even try to bang some of the Milf teachers like a little Chadlet!
4. Be a total smartass
Most of the stuff that I've learned comes from self-study long after school. Today I have quite decent knowledge of subjects like history, philosophy, foreign languages, certain areas of science, and the occult.
In the hypothetical timeline, I'd just ace exams and probably know more than my teachers. I'd speak Spanish better than my language teachers. I'd be considered a little Leonardo Da Vinci!
5. Make money by unconventional means
In the hypothetical timeline, I'd have foreknowledge of the results of famous sporting events and so I'd bet money on the winning teams and rake it in.
I'd also have some idea of what companies were doing well at that time and try to maximize my income with the stock market.
Bonus – Make a prophetic hoax
Since in the hypothetical timeline I'd know much of the future up until 2024, I would write a document titled "Visions of the Future from a Modern Prophet" and include detailed descriptions of inventions and cultural developments from the late 2000s to the early 2020s including things like the generative AI, geopolitics, elections and other significant world events. I'd distribute printed copies of the document and upload versions of it to various places on the internet just before returning to our current timeline after graduation. In time people would come to genuinely believe that I was a prophet. Or my prophetic hoax would at least become an urban legend. I'd do this just for the shits and giggles! Lmao!
All of the above if what I would do if I went back to my school days with all of my adult knowledge intact. What about you guys?
