You are young for that revelation compared to some of us. I came to understand it when I was 75 three years ago and it is helped me to re-prioritize my life and focus on what is most important? Each of us who comes to this revelation has our own list of what is important so that we can learn to live each day that we have left despite the discomfort of feeling that the road is so much shorter than we had hoped. For me it caused me to prioritise my health, no more excuses, so that I could ensure that I had the best chance of more days. But it also caused me to prioritise my relationships and focus on how I could help others. Another truth was no matter what age you are the next day is never promised. I lost my nephew when he was 14. I lost my mother when she was 46. It’s important that we know what our priorities are and that we can enjoy the day that we have been given despite uncertainty and grief. my thoughts are with you.
