How many of us (I'm obviously in) have built software because we needed it for ourselves? Example: automating scheduled invoicing from contracts, a commenting system, and a form generator.
And then...find out that it only solves MY problem.
I can count around a dozen times and got a dozen useless domain names to show for it 😲
Then what? I still need the tool, can I generalise it for the market? Is it even worth trying?
