En español | For many years I worked in palliative care. My patients were those who had gone home to die. Some incredibly special times were shared. I was with them for the last three to 12 weeks of their lives.

People grow a lot when they are faced with their own mortality. I learned never to underestimate someone's capacity for growth. Some changes were phenomenal. Each experienced a variety of emotions, as expected: denial, fear, anger, remorse, more denial and eventually acceptance. Yet every single patient found peace before departing. Every one of them.

When questioned about any regrets they had or anything they would do differently, common themes surfaced. Here are the most common five:

1. I wish I'd had the courage to live a life true to myself, not the life others expected of me.

This was the most common regret of all. When people realize that their life is almost over and look back clearly on it, it is easy to see how many dreams have gone unfulfilled. Most people have not honored even half of their dreams and had to die knowing that it was due to choices they’d made, or not made.

It’s important to try to honor at least some of your dreams along the way. It’s too late once you lose your health. Health brings a freedom very few realize, until they no longer have it.

2. I wish I didn't work so hard.

This came from every male patient I nursed. They missed their children's youth and their partner's companionship. Women also spoke of this regret. But as most were from an older generation, many of the female patients had not been breadwinners. All of the men I nursed deeply regretted spending so much of their lives on the treadmill of a work existence.

By simplifying your lifestyle and making conscious choices along the way, it is possible to not need the income that you think you do. And by creating more space in your life, you become happier and more open to new opportunities, ones more suited to your new lifestyle.
