Maybe after experiencing a bereavement you recognise how short life is and have a new appreciation for yours making sure that you do what you want to within it.
You may look back on what you have been through and recognise just how far you have come. You can develop a deeper connection with your abilities and strengths.

Perspective is changeable and there is nothing like surviving a difficult trauma to help us put things into perspective and perhaps look at life through a different lens.
