Most of us have trouble organizing our life, especially when it comes to getting clear and accomplishing important goals.
Ann Jackman's book, How to Get Things Done is a perfect guide for such endeavors.
It's a colorful book, more a workbook, that leads you, step-by-step to first identify what's troubling you and discovering solutions, then help you, again step-by-step, chart the path to making the changes that you want and accomplishing your goal.
It's a super user friendly book written by a master, someone who knows the subject so well as to be able distill it into its most essential aspects. Therefore, very effective. Highly recommended.
