Going from 0 to 3000 weekly added users is an amazing accomplishment and you should always remember that you are capable of producing something people love using.

The problem is that the real world massively compounds on small advantages. Your competitor is 1% better per day at growth, that compounds to a 37x difference in a year. You could do everything perfect except one small issue, or operate in a space where your success is easily replaceable, and none of the effort will translate to real world results.

I would do the following

1. Seriously audit what you can do/insights you have that nobody else has

2. Translate that into a moat that cannot be replicated by anyone else

3. Translate that moat into growth/retention in a niche domain that you know is more important in a way others don't
