Everyone has the ‘next big idea’. But if you’ve ever watched Dragon’s Den (Shark Tank for US readers) you’ll notice a trend (or a truth). Ideas are worthless. Anybody can have an idea, but the application, turning idea into reality, is where value is created.

Here’s an idea to get you going (or stop you in your tracks). Take your business idea and the dream you have associated with it, say full-time employment, and extrapolate how much revenue you’d have to generate in order to achieve that goal.

Chances are you’ll be surprised with the result–how hard it would be to achieve.

Of course, you can get overwhelmed and do nothing, but once you have a more accurate picture of the work it’s going to take to turn dream into reality, you’ll be able to prepare accordingly, or simply walk away.
