I’ve seen the question over and over again; what should I sell? and how much of it?
In ecommerce (and commerce of any kind) you have to find a product that people want to buy. Quite simple sure but in a free market where anyone can do exactly the same, finding a profitable product is more tricky.
My advice? I refer to a post by Chris Jones:
But if I had started my ecommerce business five years ago, my Thing would have been running marathons. It doesn’t matter what your Thing is; what matters is that you have something that wakes you up in the morning, gets you excited, and that you find yourself thinking about all the time.
Think about what matters to you, and to the world. At the end of the day, in business, you can’t win if you don’t enjoy what you’re doing. It’s that simple.
