The take-aways for me are:
1. If you become famous on social media, understand that it might not make you enough money to survive, paradoxically with more fame leading to possibly less income.
2. If you must make videos, vlogs, blogs, or whatever else online, do something that you want to do for its own sake. Make something that in itself is valuable. Don't make a song because you think it'll make you money or a branded informative video because you think it'll net you an audience and therefore income. Create something great for the sake of the greatness. That way, you can't really lose either way. Because, it seems, either way, you're going to lose.
