We recently came across Linds Redding, an art director/motion graphics artist who blogs on the tricky business of living and dying.
This is from his post A Short Lesson in Perspective:
The other thing I did, I now discover, was to convince myself that there was nothing else, absolutely nothing, I would rather be doing. That I had found my true calling in life, and that I was unbelievably lucky to be getting paid – most of the time – for something that I was passionate about, and would probably be doing in some form or other anyway...
So was it worth it?
Well of course not. It turns out it was just advertising.
