I don’t understand your position here. You start out saying some people are blocked from success and imply your lack of success with women is an example. Then you say you don’t know if your lack of success is something you can control because no one has told you exactly what the issue is.
Is your definition of being blocked anything that doesn’t just happen by itself?
Seems pretty clear to me: whatever one is trying to achieve they can be blocked (lack of money, talents, wrong country, etc.) and unless the block can be identified you can never know if it's a block that can be managed/overcome or not. Since OP doesn't really know what's wrong they tried asking for external feedback but that feedback was not actionable and it also didn't help identify what kind of block it was.
