What is the lesson here?
Don't put all your eggs in one basket. We're taught that for everything from investing to dating.
Lets say for example that you somehow make $120,000 a year over expenses with instagram (don't ask how, it's just an example). This is far more than you previously made in your last job by double. The problem is it takes nearly 100% of your working time to make this income on that single platform. Any less amount of effort and your income drops significantly. Now, you are in a trap where you cannot split your efforts between platforms, you have to go full in on one.
Your solution would be to make far less money... um, safely? Whereas a far more realistic solution would be to ensure that you don't live to close to the edge of your means and put 1/3rd of your income back in savings in case the day the platform fails/kicks you occurs.
