Let's say one in three succeeds. Then 1 of mine will succeed, and 2 of the 6 investments. But mine are owned by me, the investments are only owned in a small part by me. Still sounds like a better idea to create my own.
I think the assumption is that your startup is controlled by you, but other startups are potentially controlled by people prone to failure. The odds for your own startup -should- be better than others.
Of course, if you're prone to failure, the reverse is true... But if you know you're prone to failure, why would you try something as risky as a startup in the first place?
