Several weeks ago I started on a huge "do or die" revamp of SongBox. I tore apart the landing page (thanks to everyone here who critiqued), restructured my pricing plans, completely re-wrote the SongBox user dashboards.... I did a lot.
Since that revamp I have had hundreds of signups to the free tier and a handful of paying members! Revenue so far this month is over $100 for the first time.
It is VERY rewarding to do something where the intention is to get people to pay for your product... and then they actually do. The most rewarding thing isn't the cash, it's the fact that I've created something that people find real value in.
