Class 11 Notes Essay—Secrets
Back in class one, we identified a very key question that you should continually ask yourself: what important truth do very few people agree with you on? To a first approximation, the correct answer is going to be a secret. Secrets are unpopular or unconventional truths. So if you come up with a good answer, that’s your secret.
How many secrets are there in the world? Recall that, reframed in a business context, the key question is: what great company is no one starting? If there are many possible answers, it means that there are many great companies that could be created. If there are no good answers, it’s probably a very bad idea to start a company. From this perspective, the question of how many secrets exist in our world is roughly equivalent to how many startups people should start.
