Random thought: If you were thrown in the past when you were 10 years old, losing all skills and memory, and were allowed to bring **one** item, what would you take?

Personally a like 1tb disc filled with data about my life, advice of what to do and what not to, to improve my current life, some dates and winning lottery ticket numbers, BUY BITCOIN, and a LOT of stuff from the news since then. Imma be like a prophet, announcing every event before it happens on an anonymous account on the dark web, leaving people wondering and doubting the reality.
