You must have picked up quite a lot of interesting stuff from those art lessons in the past few years!
Although, I have not been involved in any creative stuff as such, I like and resonate with what you have said in these lines "when we are being creative, we really change in many ways. It’s like something unlocks. We are meant to be creative in some form(s)".
When my son was around 6 or so (he's 10 now), I used to instantaneously to make up some small stories for him. Recently, I wrote a story for him in Hindi as he was learning to read Hindi and it sure was a very fulfilling and satisfying process for me. Other than that, a few posts on Steemit is all the creative stuff I have done so far.
