I wouldn't really say that 'going round in circles' applies to me at all [a phrase defined here as using a lot of time and effort trying to do something, without making any progress]. However, since drawing these three birds on a plate, the idea presented itself, aroused my curiosity and here I am exploring it, albeit briefly (not wishing to spend a lot of time and effort on the subject).
It has led me to ponder the idea of progress (vs wasted effort) and how one measures it (progress). As an artist, I like spending time on something (with something), exploring, getting to know, experimenting, trial and error etc ... all a necessary part of the creative process. Sometimes you do go round in circles, coming back to the starting point, but generally with a new point of view, or perhaps (hopefully) a deeper understanding and the urge to try something new.
This is progress!
