While you should always remain grounded and know what you don't know, don't ever self-select yourself out of things. (Some things require credentials, but notwithstanding that, there are entirely new jobs and opportunities being created constantly.)

While I would expect someone to know algorithms, data structures, distributed systems, and have good taste and pragmatism for both eng design and office politics, that doesn't mean you can't learn those things. You absorb them the deeper you go and the more frequently you encounter them.

There are no real rules of the universe, and you're only here for an infinitesimally short time. As long as you're not hurting anyone, break the rules.
