Even if you were to succeed, which is very unlikely, there is a VERY high probability your 'career' will still fail. There have been multitudes of people who were 'big' 10 years ago only for their viewership to slowly evaporate and that's the best outcome possible, there are almost no long term successes.

The worst part of this problem is if they return to 'normal' work, they are now very behind in their career development. People spend decades building the skills they need to have a high paying job in their 40s-50s, what jobs are there for the skills of a former streamer? I'd say almost none, or at least none that pay well.
