Often in the creative process we get stuck. It all seems monumental and failure ever present. One of the best ways to get unstuck is by doodling.
Take a square of paper and draw a squiggle line. You can even close your eyes. Continue the line with your eyes open. Use different pressures. If you want to scribble with anger that is ok. Scribble awawy. Move out of the line and cross over a few times to make some freeform shapes. Keep going. Sometimes you will start to see shapes emerge into something recognizable. If you do that is fine,
but it is not a necessary part of the process. If you have bright colored markers the next step might be to colour these shapes. The more you work on it the more your mind will release tension. I have whole collections of large pads where I have done my doodles. I started this process years ago during a difficult time and kept up with it till I could begin again.The large doodle in the post was done during this time . Your inner critique is silenced with this. Why? Well, because the mind cannot label the result and it gives up. You end up with a fun collection of drawings that you cannot judge as good or bad. So start doodling and have fun.
