I read a fascinating quote about who you were, who you are, and who you will be.
You’re a community of selves stretched across time. – Jordan Peterson
The idea that your past, present, and future are all different people puts a different perspective on things.
It detaches you from your past, that person was a different person. Your past selves are who you can learn from.
Your future self is a person who will inherit from what you do today. Keeping that future person in mind when you make decisions will help you make decisions that work today and for the future.
In the end, we only have the present. That is where our focus should be. The more of ourselves that we bring to the present the more fulfilling our lives are.
