Creativity is one of the typical traits of ADHD. I can think about 3 ways for it.
One way is creativity in job. It could be a job typically creative, like to be an artist, or it could be a more common job where anyway creativity could contribute to do things in a different way, sometimes appreciated.
A second way for creativity could be an hobby, something we do just for our pleasure, to express ourselves outside a job that does not fully allow that.
A third way for creativity is a need. Not just a possibility in this case as in the previous 2 ones, but exactly a need that we have. In life we have to struggle because we are often outside the standard path, so we need to demonstrate in some way that sometimes yes we do mistakes, but we are worth. So creativity could be a way to demonstrate it, to reach any small success that says: look, I did this with my peculiar creativity, and it worked, I do not do mistakes only.
So, how do you express your creativity?
