Businessy "change leadership" book, and mostly repetitive anecdotal - but also a good framework and straightforward idea: we often fail to change in order to meet some new goal because we don't acknowledge how protective our current self-identity is of the status quo, for perfectly good reasons until we test out and prove to ourselves that the hidden assumptions of that identity no longer apply. Emphasis on these cultivated adaptive transformation-of-self changes, rather than treating goals exclusively as a training/skills/technical activity.
