Troy Henikoff, the managing director of TechStars Chicago once asked our Starter League students if their startups were "painkillers or vitamins?" Vitamins are nice to have. We know we should take them, but we don't always remember. However, when you have a headache, what do you do? You find the nearest Advil to take the pain away.

When building a startup, you want to create a painkiller instead of a vitamin.
