Welcome back -it has been a while since steem.chat :)

People should just post about stuff they are passionate about, take part in the community, and be happy with that.

The challenge for many is that they either don't know what they are passionate about, or think that it won't earn them money. People put the money over the value of doing what they are passionate about.

That seems to happen way too often with youtubers, and they rarely succeed if they just want to make money.

Because the audience knows that they are faking it. Though, people are pretty blind these days in regards to this, which is why so many of the social movements get traction.
