To answer the main question, you don't need to know more than what the OP posted.

The poster show's self-doubt, self-awareness, the ability to self evaluate and the ability to learn as indicated by his undergrad.

So definitely the intelligence is there. Considering the poster is most likely in their early twenties, regardless of the idea, the best thing going for the person is their runway. They have the time to fail a couple of times before other life goals come into play.

And frankly, there isn't too much correlation between business success and high intelligence. Anecdotally, it can be argued that there is an inverse relationship.
