A therapist, haha. But this was already stated here.

Otherwise?

Hard to say. I think nothing that cost me money has helped me at least as much as the things I got money for.

I got a bunch of certs, but I think they alone aren't any good. Certs, jobs, projects, customers, awards, all together form a picture that you know what you're doing. The more you show, the less people ask questions that are potentially not it your favor.
