To be 'on purpose' means you're doing what you love to do, doing what you're good at, and accomplishing what's important to you.
Jack CanfieldI used to define success as being able to produce any result you wanted, whether it was a relationship, weight-loss, being a millionaire, impacting the culture, changing society, whatever it might be, it might be homelessness, whatever, but lately I've realized that success is "fulfilling your soul's purpose."
