Upon exploration, you will find many books and resources providing specific and targeted of methods that may work uniquely for you; here is my current list of self-improvement sources:
1. Jim Quik, Limitless, much like the movie by that title, clearly demonstrates by specific examples and personal stories, that by adopting better habits, utilizing and organizing time better and using an incremental, small step approach to behavior change, you can realize significant goals, quickly.
2. Dr. Chopra, The Ultimate Deepak Chopra, provides many tools and techniques for improving concentration, mindfulness, and meditative practice to achieve milestones in improved health, wellness and inner peace.
3. Dr. Hyman, Young Forever, provides actionable diet, nutritional, and health best practices, based on relevant medical and scientific research and clinical evidence.
