What the source of anxiety around drawing?
There is no anxiety when drawing doodles or studies but there is so much resistance to making anything thats original and at a relatively high level of polish.
It’s a mental/emotional block, because I’ve done it plenty of times before but can never seem to get into the mindset of starting a piece consistently.

Where does this feeling of resistance come from and how can it be resolved without substance abuse and reliance on alcohol?
