Whether you wrote 15 applications or just one or two, does that really matter? Designing, exploring, writing, iterating on and maintaining these applications _for years_ have given you insights, battle scars and tacit knowledge that can only be gained through experience and continuous learning. Not to mention the different environments technologies and foundational knowledge you explored and internalized.
You've accumulated a hard earned skill set and the ability make wide reaching, pragmatic decisions. Do you or someone else _know_ what the _best_ way of doing things is? Probably not. But I bet you have developed opinions, taste and a toolbox of approaches with different trade offs.
That's maybe where the OP is coming from as well. The mindset of being opinionated is very valuable if you can back it up.
That doesn't mean you're always right and don't let other speak. That doesn't mean you can't change your mind or that your approach excludes other people's perspectives and incentives.
It means you can strive for _better_ and that you're crazy enough to make bold decisions when necessary.
