The latest issue  of the newsletter carries a quotation from Einstein on study. I like it very much, so that I am citing it below:
Never regard study as a duty, but as the enviable opportunity to learn to know the liberating influence of beauty in the realm of the spirit for your own personal joy and to the profit of the community to which your later work belongs.--Albert Einstein
