When I see how several painters I know here are struggling with their watercolours and paintings so that they can't see a solution anymore, I sometimes think: Friend, the fault is in your drawing. I don't regret for a moment that I did not go in for watercolour and oil painting straight away. I am sure I will catch up if only I struggle on, so that my hand does not waver in drawing and perspective.
