Don’t start a business because it’s in the trend. Consumers are flicker-minded! When Apple released first iPhone, everybody rushed to get an iPhone. When Android entered the market, everybody ditched the iPhone and rushed to get an Android phone. Then Apple came up with better iPhone, everybody ditched the Android phone and rushed to get the new iPhone.
When you start a business, it takes time to break-even, if your business depends on trends, chances are, the trend changes before you can break-even, how are you going to pay the rent you have committed for the next 2 or 3 years?
Don’t start a business based on trends. Don’t open a shop to sell iPhone because iPhone is in, or open a shop to sell Android phones because Android phone is in. Start a business because you are damn good at something. Be the Apple! Or be the Android!
