Worth noting not everyday will be like this and she does not have a constant salary like this.

This may seem like a decent life (in some cases like PewdiePie it is) but the honest truth is pursuing a real career is more beneficial (there a few big earners but a lot aren't).

It is a pretty neat way to be paid while gaming (also noting a lot of people donate then take the money back) but it isn't going to last forever.

You are going to need a job that has a decent constant salary, provides benefits, and can help you with getting a pension so when you are old you don't need to work for income and eventually her stream will die down and she won't have any of this, she may be enjoying it now but this isn't something that will benefit her future.

Also don't understand why everyone is so hateful to people like her, be edgy and jealous all you want but she found a very good way to earn money and is utilizing it efficiently.
