A very good friend of mine explores as professor for psychology the significance of emotions in therapy: They are complex, context-dependent and based on inter-personal experiences.
The crucial point is that patients with emotional disorders do not only show dysregulated negative but also a deficiency of positive affects.

The same holds true for many clients in business coaching: They are much more focused on things that from their perspective go wrong or cannot be achieved rather than celebrate their accomplishments or appreciate their skills. 

An example: Bob is very successful but afraid of presenting in front of his management board – the table below shows different techniques of coping with the underlying emotions. 

Mindfulness and meditation are useful practices to stimulate a positive attitude – stay healthy and confident … 🙂
