The absence of the usual equipment is a great exercise. It’s a creativite constraint forcing you to find new ways to do old things. On the other hand, acquiring new tools or more powerful versions of old tools is giving a boost to the desire to create. Once the initial curiosity of the novelty fades away quite quickly, (there’s a connection here I need to remember) what comes into play after is the increased speed and flexibility in executing the usual creative rituals.
So, to keep your creativity alive try both: limit yourself intentionally to appreciate the value of your old dear tools and acquire or upgrade your old tools to get a creativity boost.
