Why it is a good idea to keep a notebook

I regularly flip through my little notebook (which I have with me at all times) and every time I find that keeping a notebook is a great way to keep up the good practice of drawing regularly, form ideas, think about compositions and find inspiration. Below are a few examples of sketches on the go, drawn while travelling through the English countryside, in Canterbury Cathedral, Dover cliffs, Paris etc. (see also the Landscape Paintings page of the www.dutchoils.com website).
