Make decisions, and NEVER look back.
I have been thinking of the purpose of life since my late 20's. Not sure I got the perfect answer, but I'm reaching a point that I feel comfortable using it to guide my daily life and share with others.
Instead of purpose, there was a mental shift for me that told me maybe the purpose is not the goal. There is no endgame. From a grand scheme of the universe, time is meaningless. From the recent rapid development of Artificial intelligence, we may all just be in a big simulation. Nothing is real. So then what is the purpose?
