You don’t learn to walk by following rules. You learn by doing, and by falling over.
If you really want to make a company that will survive, you focus on making good products. If you care about making good products, eventually, profits will follow.
Nothing in this world can take the place of persistence. Talent will not; nothing is more common than unsuccessful people with talent. Genius will not; unrewarded genius is almost a proverb. Education will not; the world is full of educated failures. Persistence and determination alone are omnipotent.
