I can’t agree with this more!
In my 18-year freelance career, I’ve seen over and over again how specialized generalists thrive. Whether you call that “T-shaped” or a “deep generalist” they all mean that you’re exceptional at one or two things, and have a broad range of supporting skills to back that up.
Technology changes so fast. You have to be able to adapt and slowly evolve your speciality as your most valuable skills morph with the times, trends, technologies, and best practices.
I credit much of my ability to have a sustainable freelance career to being a specialized generalist. And every time I talk about business or design I’m always encouraging people to use the same formula.
Thanks for describing this situation with such clarity and great examples.
