Whilst I understand the term, cognitive-dissonance in psychological terms, I see many likewise terms (buzz words used more to dismiss people's views.

Art does not have to cost anything and it need not have any views other than your own. Your posting in here and the words you use can be an art form. Your daily activity can also be an expression of art if you take the time to be beside yourself when going from one moment to the next. Points 1 & 6 from @TheGal 's Google Search result hits on this. As for those other points, imo they just lead right back into the dissonance.

By knowing yourself, you won't need anything to be creative because once you care less for the monkey that keeps you bound, you'll grow tired of being tired and start to feel the morning light. I have no brush or art supplies in hand whilst looking out from my sun chair when I manage to get out of my room. I'm literally running on fresh air as I contemplate whether it's worth breaking out a sketch pad or canvas from the reject shop ...

I used to pay a small fee to sit with the elderly where the paints and pastels were supplied.

It's interesting that you mention the obsession component with supplies - I get caught up in the finer details myself ... those elderly folk helped me see that and taught me to relax.

Now I just struggle to get out and look into nature, but when I do ... I find for me that is enough.

Good luck with whatever activity you're able to muster up. Points 1 & 6 really help. Sitting outside helps me be self-aware and when I can I am thankful that I was able to do that for myself.
