Anything that won’t sell, I don’t want to invent. Its sale is proof of utility, and utility is success.
Thomas A. Edison
All to often we inventors can get caught up in our heads with inventing for the sake of it. ”Wouldn’t it be cool if this bottle opener had another bottle opener on it?”
While this can be a fun exercise, make sure to take the time to evaluate the market potential of all your ideas before you choose the one to really focus on. Only when you clearly understand the size and taste of your market, as well as why your idea is truly better than the competition should you start putting in the time and energy.
Creating cool things is a fun hobby, but if you’d also like to get paid for your efforts, make sure you choose through research rather than emotion.
