Multiple revenue streams is horrible advice for a beginner. You do not want multiple revenue streams. When you are beginning you need one revenue stream that is really good. If you look at almost every billionaire didn’t do many things at first. They made their first million on one thing. Then they get a little of money then they grew into other things and diversify.
Focus attention on one thing and dominate it first
