6. Trying to blow up too fast
It's good to want to expand your brand and get placement in stores around the world. However, it's best to grow at a pace you can maintain, unless you end up becoming ubiquitous too quickly, and therefore, mad corny. Limited distribution isn't the same as limiting distribution. Forge organic relationships with stores you could really see the brand doing well in, and respect those relationships. Nothing's worse than being able to buy the same brand at three or more shops within a five-block radius. That screams "sell-out."
