There's probably room in your life for both. Keenly becomes another side project.

The smart money though is on the thing that's working. Take the time to understand why it's working, and how it might grow future wise, and user wise. This is not fun like programming but makes the things you build more successful.

At the same time put some limited hours into keenly. It makes a good distraction, and we all like a change from time to time.

Always remember that building things successfully takes multiple skills. You've got the programming down, but learning the rest can be just as satisfying.

And don't be scared to ask for help. There are lots of successful people around you who can help if you just bother to ask.
