I hear you and hope you find your way back (if it is your wish).
For me the "loosing" is mostly a result from pressuring myself, from having counterproductive thoughts like 'is this good enough' or 'is this better as the last...' Thoughts which perhaps everybody must fight with. These thoughts often seduce me to choose secure topics for my paintings which I later regret, because for me they are boring. Giving myself the permission (for example through little exercises like the one described above) to fail, to make mistakes or produce utter rubbish, frees me up. Do you have an idea why you have the feeling of “lost mojo”?
Another way back maybe the complete contrary approach, namely to simply do it: tackling everyday a small (technical) exercise, like strength training. Something you can do fast and which does not involve to much freedom (which could invite overthinking) So that painting/sketching (or your preferred technique) becomes an automatism.
But as said above, I do not know your situation and perhaps sometimes taking a break is the best way.

Thank you for the encouraging words. I think I'm mostly stuck in the "this wont be good enough" mentality since I can be a perfectionist at times. I need to just get up and do it though because how else will I create and learn?
