I think the other comments were interpreting this as "where did you find the time?" rather than "where did you find the other resources to support that time?" (e.g. money and motivation). I've been maintaining a huge FAQ since I've gotten these questions a lot over the last four years, and this one in particular should answer the question: https://github.com/Adam13531/BotLand/wiki/FAQ#how-are-you-af...
I linked that rather than copy/pasting it because you may find other answers interesting on that page. :)
EDIT: I should clarify that 5000 hours is roughly the number of hours that I streamed, not the number of hours that I worked on Bot Land. There were way more hours spent in the background doing all sorts of things (including coding), but the majority of the actual development was on-stream.
