It depends on how much your save during those months and what quality of life you expect to have. It's possible to make things work here on a very small amount of money though
As for YouTube, or video blogging, a huge thing that prevents us from really considering something like that is technology.
We are also working to make a living through steemit. Our time is currently dedicated on making money mostly, so ventures not bringing in capital are not prioritized.
I may write a post soon about our budget though, as we have one of the tightest budgets but we are still making it and living pretty decently
