I started playing in 2003 or 2004 at 8 (I am now 24) and didn't speak English so I was incredibly inefficient for the first few thousand hours. And yeah, I pretty much spent my time wasting it in house parties, chasing unrealistic goals (like visage for dfs) while being underleveled for it to be sustainable, sucking at PKing and Bounty Hunting and watching guides looking for ways to be more efficient (without actually applying them). I actually got 26k hours by the time I was 16, played on and off till I was 20. Got 99 prayer in my last year because I finally discovered I could watch Netflix at the same time as playing.

If you really want to bet that 1b, I can go through the trouble of producing proof :) I'm sure my friends who still play will enjoy that kind of money
