Like chocolate, journaling can be stimulating and deeply personal, or in the case of graphic design superstar Stefan Sagmeister, deeply public.

If you're in need of some introspection or inspiration, check out Things I Have Learned In My Life, So Far. The creative project encourages reflection, journaling and offers more than a few nuggets of wisdom to chew on.
