You need to come up with something, but you can't come up with anything.
How do you solve that?
When I was in a creative agency, many times, I felt like without any solid idea how to do things differently. I realised how other people attend many events or places where the art is. Since then, I tried to "train creativity".
Some of the activities I did and I am doing are:
π brainstorming with friends (or ChatGPT)
π reading books (I tried to incorporate fiction)
π creative writing or other methods (eg Six Thinking Hats)
π taking up some activities related to creation: photography, drawings.
π above mentioned attending creative events and places (galleries, concerts etc)
