live for today,
nor for yesterday.
time is a hallway of doors and your goal is the end. you cannot go back or better yet; why would you want to? you have already experienced yesterday; why do it again? today is the door directly in front of you. focus on it. open it. and pass through with new knowledge. passing through today you will not see tomorrow. you will still see today and the door you just went through will become yesterday.
you cannot possibly see the future, you cannot change what has happened.
so just focus on what is already in front of you and forget all worry.
amazing. such a good writer!
