Why is it some people are in love with the idea of painting and drawing, of being creative, but only ever talk (with great enthusiasm, and often at great length) about doing so, never taking the first step towards doing so? It’s too easily more comfortable never to try than face the possibility of failure (and success).
Fear your expectations won’t be met, that your paintings or drawings won’t be “good enough” (“What is it?“). Fear others will laugh at the results, or be patronizing (“That’s delightful dearest”). Fear of being perceived as wasting time and money. Fear you’re not as creative you think you could be. Fear you create something wonderful by accident and can’t repeat it.
There will always be a gap between what you’d hoped to create and what you do, something else you could’ve done to a piece. That’s not the same as never achieving paintings you’re really pleased about. It’s an idea/goal for next time.
There will always be people who don’t get it (neither the desire to do it nor the results) as well as the “my cousin thrice removed also paints pretty little pictures without any effort at all” brigade. Smile (in the British stiff-upper-lip tradition, not a manic grin) and move on. Their judgement of what you’re doing is inconsequential. It’s your time and money, you can decide how to use it. Someone criticising is wasting their own time.
Creativity, like most things, needs regular exercise and stimulation. Skills and techniques take time to learn, they’re not going to fall on your head like rain and soak into your brain without effort. Professional artists don’t display unresolved and failed paintings, that’s why it seems everything they produce is of a certain standard. The elephant in the studio is that these fears never go away completely, and new ones come along, you just squash them under a growing pile of artwork.
