I was reading a business book recently and it had a list of attributes that an idea might have if it is an expensive hobby rather than a sustainable business. Taking this idea one step farther, an original expensive hobby is probably somewhat common.
For example, imagine that you have an idea for a great product but after running the numbers you find that it would never be a sustainable business. Maybe your friends and family think it is such a great idea but when it comes to laying down the money for your great idea only you want it that much. Thanks to additive manufacturing and other custom manufacturing it just might be possible to make a one off of the product.
Plus, actually going ahead with the idea instead of making excuses gets something done. Additionally, after making something, having a functional prototype, you might just find that there is a business behind that hobby.
I mention all of this because I have an idea that might not be a business but after realizing it could be an expensive hobby I had no excuses left for not working on it. I have done more on it in the last three weeks than the last three years. It is one of those moments I thought, 'why did this take me so long?'
