Life is not meant to be an organised event where everything goes like clockwork, and we can expect to achieve 100% success.
The truth is we are unable to control our life. Life is messy. This is the nature of life. Do not aim for the unachievable.
We could have 70% of getting it right and we should accept, allow and embrace these 30% of imperfections. We can always learn and grow from these painful experiences.
Ajahn Brahm encourages us to open the door of our heart to the nature of life as it is. He said, "Do not disturb the nature of life and life would not disturb you."
