The magic does not lie in your choice of film.
The magic lies in what you do with it.
It's amazing how much we learn by exploring the absolute limits of our materials, by working with all sorts of ways of treating it. I claim that if we change materials often then we never really learn them fully, but we just scratch the surface.
I'm very grateful to have learned a lot from experienced mentors over the years, with several hundred years of photographic knowledge combined, many of them with several decades in print making and portraiture, and the approach that has forwarded my own art and print quality the most has been to dial in my film exposure and film development so that it fits the paper and paper developer that I use.
The amount of variation I can get by treating film exposure, film development, and how I print, goes very far beyond what can be achieved by switching films. It gives infinitely more creative freedom to have this knowledge than to have an arsenal of different films, supposedly with different 'looks'. Basically, don't lock yourself into believing that switching materials will somehow transform your photography. The only thing that will happen is that you'll be swearing for a while when are in the process of figuring it out, and then you'll arrive at pretty much the same point you left off. Creativity and inventiveness must come from within, from you brain, your intellect, your emotions, and your heart. That is what I call keeping it fresh, alive, and truly creative. No materials can ever substitute for that.
The biggest mistake I ever made was to experiment with many different films and film developers, because it was frustrating beyond belief to get a good print from so many inconsistent negatives, and resulting in a lot of darkroom waste, and prints in series of photographs that look terrible together as a group. But the worst part was that I ended up being so focused on the materials themselves that I forgot about the most important part - the subject matter. It ended up being a huge distraction and an obstruction.
Again, the magic lies in what you do with it, not what materials you choose.
