I'm not very verbal about my accomplishments but I've been lucky to have previous managers recognize my work and place me as tech leads for the team. How did you become CTO for ITWatchDogs? Is it something I should be actively networking on in my group to find a good fit?
Generally executives are "go getters" by definition, because those jobs are competitive and therefore competitive people get them. But there's no rule about that, and certainly no rule about personality types being important for being a mentor.
By definition, if you're not outgoing and not "out there," thus people don't know who you are, they'll never have a chance to know that you're on the market for being an executive or a mentor, so in that sense yes, you'll cut off your avenues for getting into those positions. But I don't think it's an important factor to be good at those positions.
(Perhaps the world could use more mentors who are less confident and self-absorbed!)
Appreciate your time and feedback Jason. Haha agree, some executives I've met were a bit aloof with their superiority complex.
