Possible ways wisdom comes to us:
Through reading and study.
Through mentors who challenge us and teach us.
Through life experiences which is probably the best way to gain wisdom.
I am retired now, a full-time writer. I still actively do retreats. I love the works of Thomas Merton and my new book, "Spiritual Journaling -God's Whispers in Daily Living" is available on Kindle and Amazon. http://amzn.to/qQz6Ng
