I want to build a product which can let me leave my full time job and support me financially. I have built a lot of products over the past (http://www.websrvr.in/ http://www.websrvr.in/ , https://zammu.in/ https://zammu.in/ , https://getsimpleform.com/ https://getsimpleform.com/) but none of them have allowed me to work on them full time. I should probably spend more time in marketing/selling the products.
