Try to take a step back and look at your situation differently -- If you boil it down, you are essentially complaining about gaining traction.
Countless entrepreneurs would love to have your problem. Even in your 'fun' projects you have shown a real knack for delivering something desirable and useful enough to gain traction.
The traction results in an increased support workload. On the technical side, the traction results in an increased server workload. Since you are not profiting from the traction, you are unable to scale.
You get the same amount of time in each day as everyone else, so if you don't plan to scale, the time you have will become impacted with things you would rather avoid.
Selling off your side projects is an answer but it is not the optimal answer. A better answer is two fold; (1) find a way to profit from the traction, and (2) use those funds to hire someone to take care of some of the added workload.
Every successful entrepreneur learns to manage the constant cycle of acquiring new responsibilities and then delegating those new responsibilities to others. Since you can only fit so much food on your plate, the answer is to keep adding people holding empty plates.
Also, if the side-projects are generating profit, then use that to hire people (for support, etc.)
And lastly and perhaps most importantly, send me an invite to Forrst!
But the first, absolutely first, "action item" is "Send mindcrime an invite to Forrst." Do this and all else shall become clear. ;-)
Its nice that you have side projects that are growing and doing well, but realistically, you have to look at the hard reality that they'll probably fade in time. You gotta stick with your main bread winner, and that looks like Forrst.
