Sweat the Small Things

“If you let yourself become absentminded even for a short time in your daily life, when an emergency occurs you will forget your usual presence of mind. Even striving your very best, a single small thing will cause ruin. We cannot know when an emergency will occur.”
What this means is that unless you are careful about the trivial things, even great blessings will be destroyed. This is a most serious passage.
