Another chance

A dear friend of mine has a brain tumor. He wrote me to tell me yesterday, and it really shook me up. You need to ask yourself, what are you doing with the short period of time that you have? This person has children, and a new wife. He now has to confront his mortality, and he is handling it very well.
It made me realize that it is important to live your life every day. Stop complaining about what you don't have. Start being grateful for the day, for friends, for life.
All of this is already known, but the illusion that is life gets in the way and you start acting on auto pilot.
My friend's illness has made me ask myself, what are you doing to create and keep joy in your life every day?
Thank you so much for teaching me something from this situation.
