Interesting quick read. The mix with strangers and help others I agree with strongly. You need to push yourself out of your comfort zone and do things that don't necessarily benefit you. The one I disagree with is not taking a break. If you keep pushing forward without giving yourself time to rest properly, to recharge, you will burn yourself out.

Just read a good book for professional creatives called, 'The Accidental Creative.' I highly recommend it :)
