Thought of it many times but truthfully, this would be a labour of love. Bringing any external financing to it will inevitably pressure you and put you on a schedule which will immediately and effectively destroy all my passion for it. 
Plus I am not in a good situation finance-wise – no savings (although the job pays kinda sorta okay). So can’t really just stop working and go chase that dream.
Sadly, a lot of such good ideas get drowned and eventually killed by our needs for survival and stable home. My ideas will likely meet the same fate. At least it looks like that so far.
