You Are Entirely Your Future
You are entirely your future.
Not your past.
Past is already over. You are still alive.
Your current functioning is dictated entirely by what you want in the future.
If you don't want anything from the future, then the past takes its place and role-plays as you.
All measurements of status, record-keeping and competition base themselves on what has already happened. With zero awareness of what can be.
You are "what can be".
You cannot be miserable if you are working towards something worthy. If you are, then it's not worthy enough, not noble enough, not grand enough by your own standards.
But once you know this truth you know either the goal is the problem or the pace of the progress towards it.
