An Australian nurse who worked in palliative care recorded the top things that dying patients regretted in their lives during their final months.

5. I wish that I had let myself be happier.

"This is a surprisingly common one. Many did not realise until the end that happiness is a choice. They had stayed stuck in old patterns and habits. The so-called 'comfort' of familiarity overflowed into their emotions, as well as their physical lives. Fear of change had them pretending to others, and to their selves, that they were content, when deep within, they longed to laugh properly and have silliness in their life again."

Live with no regrets my friend.
