Think About Your Death and Live Better 

We banish death from our thoughts. But this leads us to make choices in life that actually curtail our happiness. People who express more regrets tend to be those who postponed profound activities that yield meaning, such as practicing religion, appreciating beauty, or spending more time with loved ones.

This is probably because they realized too late that they had implicitly assumed life would always go on and on, so there’s always time to do these meaning-filled things. When we avoid thoughts of death, we unconsciously assume that tomorrow will look a lot like today, so we can do tomorrow what we could do today. But when we focus on death, that increases the stakes at play in the present, and clarifies what we should do with our time.
