We shall suffer no attachment to literature, no taste for abstract discussion, no love of purely intellectual theories, to seduce us from our devotion to the cause of the oppressed, the down trodden, the insulted and injured masses of our fellow men.

Hammer down product fundamentals first. Make sure you've got something that works before doubling down on promotion and marketing. Create a groundswell of organic support, and only then leverage PR and advertising to spread the word.

People have this idea that the more pious and devout I am, the more successful I am. Which is very dangerous. If you look at faith in that way, you're bound to fail at both - spiritually and in your career.
