Time and time again we see that placing eggs in one basket is not smart. It's unfortunate that most of us have to learn it the hard way. Diversify and have something to fall back on, or else when your cash flow gets fucked for whatever reason, say goodbye to your business and hi-ho, hi-ho, it's back under the thumb you go. Hope you don't have creditors...
In the meantime, it's time to start working your fucking ass off night and day. By the time you're able to settle down again, you'll probably be in a much better position than you were before.
