Learn to let your intuition-gut instinct-tell you when the food, the relationship, the job isn't good for you (and conversely, when what you're doing is just right).

Intuition and concepts constitute... the elements of all our knowledge, so that neither concepts without an intuition in some way corresponding to them, nor intuition without concepts, can yield knowledge.
