I came from a non-tech background. With help of my friends and family, took my idea and made a mobile word game Word Hookup
iOS - https://apps.apple.com/us/app/word-hookup/id1467012830 Android - https://play.google.com/store/apps/details?id=com.wordhookup...
It didn't amount to anything for some time. Luckily it got featured by Apple as Game of the Day. That changed everything, and it continues to provide residual income a year hence. The money is not yet enough or close to a full time job, but I am now working full time churning out and about to launch more games!
