I once visited a weekly painting group ( who had a great artist as teacher)and realised ,uncomfortably , that some of the students had been attending that group for years , and were still painting at the same level as when they began. That's all fine and dandy if it's a social get together, but pretty pointless if you want to become a better painter. I have been fortunate to have some tough teachers along the way, who constantly lifted the bar on me, so I would like to get others to try harder too. The look on someone's face when they realise that they can do something they didn't think they could is amazing - and what keeps me trying to pass on what I know.
And if it's any comfort, I still scare myself quite often too! This morning I was out painting on the road to Mt.Robert - I always take a deep breath when I set up my easel in public- will I make a total fool of myself? Five minutes into it and I really don't care ....I'm going to do my best and enjoy myself. And I did.
