How many start-ups are based on the idea that their business fills a niche market? And how many of those niches are actually the owners hobby or favourite pastime?
It is great to start up your own business and it can be liberating but business can be a cruel mistress at times and before you commit money and time to setting up make sure that there is a sound economic basis for your decision.
If you want to free the entrepreneur that lurks within you don’t just look at your hobby and assume that you can make money from it. Make sure it is viable and then go for it.
