Advisor suggested I should go ahead and to start my next venture concurrent with my 3 yr earnout on the company I'd just sold. Long story short, my idea + my money + 25% of my time + nontechnical cofounder getting salary and 40% sweat equity = 9 mos of dev turned into 24, launching after several competitors, all seed money burned on dev, no money for marketing, slow sales ramp, running out of cash, selling my stake to another investor for 50% of what I paid. Company still exists, cash flow breakeven, but my equity is all but washed out. Had I focused 100% I would have 100% of a very nice micro ISV.
