Mechthild of Magdeburg (1207-1290) was a German mystic and leader of an abbey during the Middle Ages and she wrote:
How You Shall Conduct Yourself:
When you pray, make yourself humble.
When you make your confession, be truthful.
When you eat, be moderate.
When you sleep, be modest.
When you are alone, be faithful.
When you are with others, be wise.
When you are taught good habits, follow them.
When your bad habits are reproved, be patient.
When you do evil, see mercy.
When you are vain, fear yourself.
When you are sad, have great comfort in God.
When you work with your hands, work swiftly.
So you shall drive away evil thoughts.
“Go in by the narrow gate. The gate that leads to destruction, you see, is nice and wide, and the road going there has plenty of room. Lots of people go that way. But the gate leading to life is narrow, and the road going there is a tight squeeze. Not many people find their way through.” (New Testament for Everyone Version) Jesus
