I would recommend for productivity Succeed: How We Can Reach Our Goals by Heidi Halverson and Switch: How to Change When Change is Hard by Chip and Dan Heath. The Procrastination by Piers Steel is also pretty good but lukeprog’s summary of it on this site basically contains all the useful information.
For depression, Feeling Good: The New Mood Therapy by David Burns. I can’t recommend this book enough.
