I just launched my project officially and it&#x27;s generating some revenue for quite some time now (small amount though). I first started working on it 2.5 - 3 years ago, but it wasn&#x27;t full time, it was always a side project.<p>It&#x27;s only me on the project, the whole time.<p>I don&#x27;t really have an advice, just work on it and don&#x27;t give up, as long as you don&#x27;t give up, you haven&#x27;t failed.<p>I wish you a good luck and a lot of persistence!
