An excellent overview of the principles and strategies for self-improvement, but short on detailed instructions on how to implement the ideas.
This author clearly enjoys using mnemonics and anagrams at every opportunity.
I enjoyed the section on OATS - Objectives, Aims, Targets and Success, but was looking for more examples in modern business and lifestyles where Objectives were linked to vision and mission, leading to aims for the project in terms of deliverables, which then could be broken down into specific tasks in an action plan, leading to the end goals/deliverables.
The ideas in the WELLSAID [ another mnemonic] section were well explained, as was the idea of using self-coaching techniques for personal development. This section would have been more useful if placed after Self-Authorisation, showing you how to select the best way forward from a current position.
Overall, very thought provoking, but not complete.
