<i>I am sure lots of you have seen all those videos/tutorials/articles about side hustles and how they've developed 5-6-7 income streams, etc.</i><p>As current standing, undefeated, unified, undisputed World Champion of Spreading Oneself Too Thin (and failing a lot as a result) my opinion is that these people are simply lying. Look hard and I bet you'll find most such claims are accompanied by something for sale, where the "something" is some sort of "information product" which purports to help you "make big money fast" or something along those lines.<p>To a first approximation, assume that nobody is actually managing 5-6-7 income streams... at least not where more than 1 of them actually amounts to anything. The ones claiming to do so are probably just trying to hustle <i>you</i>.<p>Is there an outlier here and there? Sure, probably. Is that realistic? Hell no.<p>The only regard in which it makes sense, IMO, to pursue that many projects simultaneously is when you're just exploring the search space in a manner akin to pouring water into a container and finding the low point by observing where the water pools. That is, put attention into many projects <i>early</i> but as soon as you see which one which shows evidence of being the best, aggressively prune the others and put all of your attention behind the winner. Maybe you have to iterate a few times and narrow things down in chunks, but still, the goal should be to get to a place where you "put all your wood behind one arrow" so to speak.<p><i>The fact that I haven't earned a dime from any of the side hustles so far and gave out lots of money for ads is making the things even more frustrating ...</i><p>It's a minor nit, but I'd encourage you to stop thinking in terms of "side hustles" altogether. Calling it a "hustle" implies something of low value, which merits low levels of attention and discipline, and depends more on lucky circumstance than anything to succeed. I'd suggest thinking in terms of building a business, and envision scaling it as far as (it can go|you want to go) possibly to the point of being acquired or having an IPO. But that's just my opinion...
