Good read. The book carries strong message - reduce amount of inessentials to clear space for valuables. "If the answer isn’t a definite yes then it should be a no." 4 of 6: for clarity of the ideas, slight repetitiveness, and good amount of wisdom quotes I like.

TO ATTAIN KNOWLEDGE ADD THINGS EVERY DAY. TO ATTAIN WISDOM SUBTRACT THINGS EVERY DAY.
