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.

> Is your definition of being blocked anything that doesn’t just happen by itself?

sigh... really ?
