Well for me, it does come down to the exploration.
The way my journal helps me find out totally new things.
It is certainly not about making a pretty thing, although when it is pretty, I admit that it pleases me.
I am starting to understand that the expectation of "pretty" actually interferes with the finding out of the new.
Creativity takes courage.
It takes being able to mess up and make mistakes.
That is something you don't seem to be taught in school much these days - it all is about performance and achievement.
well, please know that your journal is a place where achievement = experiment.
Make a mess.
Find something new.
"Creativity is the residue of time wasted." --Albert Einstein
