Two books I highly recommend for creative problem solving:

Kelley & Kelley's book, Creative Confidence.



Morgan, Lynch and Lynch's book, Spark: How to Lead Yourself and Others to Greater Success.

Chapters from Spark I recommend for personal creative problem solving:

3. The Four Keys to Being Credible
5. Act with Intent: Make Decisions That Matter
7. Build Your Confidence
8. Demonstrate Consistency

It's a book with the lens of leadership in an organization, but hey, we're all leaders of our own lives. No one else can LEAD us unless we let them MIS-LEAD us. Am I right?
