Well for me, I just fell into it. I was a .NET developer and ended up working for a company that taught me a niche skill (CTRM/ETRM). I then learned how to customize two of the larger applications in this field.(RightAngle and Allegro) Now I do some development but it is more implementation/integration/customization. My development skills definitely help, but its not the main focus of my work anymore.(unless I start a hobby project)
I think having a niche specialized skill certainly helps, but you could probably find work at a "big 4" firm without it. Being either technical or functional AND personable helps. I am pretty easy going so I can get along with most, and have a pretty positive attitude most of the time. That said Im not overly extroverted, so that isnt a requirement. If you want to do it, work towards making it happen. Linked in(for better or worse) can be a good resource here. Join a professional group there, go to hh events, make connections. I dont think it is a tough field to break into.
