What is essential for mental and emotional well-being?

As posted by Psychology Today:

Research suggests that psychological flexibility is essential for mental and emotional well-being.  It helps people navigate distress and create a meaningful life.  What does psychological flexibility entail?

1) Awareness: noticing what's happening in the present moment and the thoughts/feelings that emerge.
2) Openness: allowing for difficult thoughts and feelings--without needing to change them before moving towards a decision.
3) Valued Engagement: knowing what matters to you and taking steps towards your goals.

In order to operate in a place of awareness, openness and valued engagement, one must be able to self-regulate their own emotions, and have healthy boundaries within oneself and others.  When trauma presents itself however, attachment injuries may show itself in various ways, thus making self-regulation even more challenging.
