I think I will be fine regardless of the level of success that I achieve.
Ideally, I would love to create content earned enough subscribers to make some extra money but if it all amounts to nothing I will of had some fun and learned a lot during the process.

I don't ever embark on adventures expecting failure but rather jump in with both feet and try to achieve a good result. If I fail to achieve that I typically will try again with another approach or idea.
