I suffer a bit from imposter syndrome, so I completely get what the GP is getting at, it was just phrased ambiguously.
Here is a disambiguated version: "Imagine what a privileged, entitled, overconfident, upper-midlle-class cishet white dude would do, and do that."
When you speak, people pay attention! Comic books pander to your adolescent fantasies! Your doohickey is the greatest thing since sliced bread! In fact, it's the greatest thing since unsliced bread! You're a frickin genius for dreaming it up! Your LoMoSo strategy is going to make billions for you, the few early employees that don't quit, and the VC that you choose to let invest! You're making the world a better place through scalable fault-tolerant distributed databases with asset transactions! The world is your oyster, and everyone who laughed at you in high school is going to be sorry! Bwahahaha!
Er, ahem. Pardon, got just a little carried away there.
Anyhoo... that advice has nothing to do with capability, talents, skills, or accomplishments, and everything to do with self-promotion and attitude. If you don't toot your own horn, who will?
