It sounds to me like you had two successes out of four attempts. That's actually an unusually high success rate!
If I'm reading it right, your two "failures" (scare quotes because I'd count the 2nd company as a half success) are the VC backed ones. VC backed companies are a particular kind of business -- maybe that's not the style that works best for you? But that's not the only (or necessarily the best, depending) approach to starting a business.
