I read recently an advisory, suggesting that looking back over achievements and adversity whilst considering the key benefits and challenges can support forward planning. This is in understanding better what the elements were that brought you to be where you are today and how these may take you forward. When it referred to looking back, it meant with a lens of self evaluation, not pointing fingers of blame or crediting others, but really seeing what the internal response was and how this affected the outcome. Look out for patterns that may emerge and what you might have done differently for taking forward, and again, whether there is a pattern to that too. Are there new skills needed? Elements of emotional intelligence that need work? Are there common situations that bring out the best/worst in you? All questions that support positive change, but also define recognition to flag any potential repetition in the future.
Reflection can be really positive, but it is essential, to glean benefit from it to do so with a self-awareness hat on, to derive emotional intelligence and learning.
