Meditation and Drawing
It's very easy to get pulled up into your head, and into your ego, when drawing. It happens to me a ton -- I can be very hard on myself about how technically "good" my drawing is, to the point of driving myself crazy. Countless times I've not even let myself warm up (Please don't ever do this! Warming up is 100% necessary and you can never have every drawing be good, there will always be ones that don't turn out). There have been so many times I've drawn with this type of attitude that it had become automatic. For the past few years, I have tried specifically to curb this, and it's still a struggle!
This is no way to treat yourself, in anything really, but in art too. If you do it enough your mind will follow the pattern and do it for you. If you're there, meditation really helps.
There's a particular practice that I've found helpful, and it generally goes like this (I am no expert, this is a very basic step-by-step for this technique):
1. Find a quiet space to sit
2. Sit comfortably, with your back straight
3. Gently close your eyes and take a 3-4 deep breaths
4. Bring your attention to the space between your thoughts
5. Observe your thoughts, and let them go
The goal here is to not judge your thoughts, though this takes a lot of practice. If your mind wanders off, bring it back gently and with kindness. This takes a lot of practice, but the more you do it, the more your mind will do it without you specifically trying to. Paying special attention to the space between your thoughts can help foster a sense of calm and stillness.
When drawing, it can be helpful to remember this technique! If you continually get wrapped up within your thoughts, it's impossible to draw well or be spontaneous and creative.
Additionally, you can use a piece of paper or a piece of digital paper to draw completely freely, while making an effort to not judge your drawing. Just put down whatever comes to mind. You don't have to draw anything specific, you can draw shapes or forms or whatever you like. It helps to set an amount of time to do this (I generally do this for 10 minutes). Once you're done, you should be in a better place to draw overall!
