If you are spending years being proud of what you did in the past – when you where young, when the world was different – instead of being proud of what you are doing now, in the present, you will end up having spent part of your life stuck. Creating nothing new to be proud of in the future. What a waste of lifespan.
The present time is still the sum of all your past experiences. The more you’ve done, the more fully you’ve lived.
Do you really want to end up with the same result summing up your past experiences now as in ten years?
Was that far glorious past worth the emptiness that followed?
