I've known entrepreneurs who were not great salespeople, or didn't know how to code, or were not particularly charismatic leaders. But I don't know of any entrepreneurs who have achieved any level of success without persistence and determination.

The truth is, success often occurs for reasons we don't expect, under circumstances over which we have little control and sometimes unrelated to our own efforts.
