A reason, a season or a lifetime? : the importance of positive collegial relationships and networks in establishing career sustainability and resilience

Editorial. There is a saying that people come into our lives for a reason, a season or a lifetime (author unknown), and we argue that this idea can also have currency in the professional realm with colleagues and other professional connections. As an editorial team, we are geographically distant from one another and between us, we have had successful international careers that have spanned clinical, administrative and academic environments. We have faced our share of challenges along the way. In preparing this special issue of the journal, we reflect on our own careers; the importance of developing and maintaining positive, strong and resilient collegial relationships and the role these relationships have played in our own careers.
