Our work/career can give us purpose and is often part of our identity. This article was a useful way to check in about our relationship with our work. It mentions that we can be trying to find comfort through our work and if this is our only way of getting this perhaps we can check in with ourselves. Good to know that overworking may not mean we are better at our jobs!
Cognitive Analytic Therapy provides a useful framework in thinking compassionately about what work means to us and how we may want to add to our way of feeling good about ourselves.
