I'm really enjoying Dear Design Student a blog written by designers, ostensibly for designers and particularly young and student designers. Blog entries range from the practical (don't give two weeks' notice - give enough notice to wrap up your projects and make a clean exit) to the abstract (Doing the right thing the wrong way). And in some cases like this entry they wander into the philosophical. I've long thought that design was as much an avocation as a profession and here Arjun Basu lays out the basic problem - if you live in a bubble of any sort then you're doing yourself a disservice, both as a designer and as a human being.
Being very introverted myself and making new friends slowly at the best of times this is kind of tough advice for me to read. But that's what makes this an interesting blog.
