Is your earnings solely from Adsense?

Here's a BIG QUESTION: Is your earnings solely from Adsense?

If you are, then you might be in a risky position.

Remember that the money is never yours unless Google writes a check on 23rd every month.

At any time, they can close your account due to whatever funny reasons.

So, remember to venture into other businesss, let Adsense income be your 'side' income.
