Measure what can be measured, and make measurable what cannot be measured
Work, look for peace and calm in work: you will find it nowhere else
The one who steps back will not progress
Those who make fun of you, those who try to get rid of you, they are the people whose applause you most often seek to obtain.
The worst sin is that which the sinner takes lightly
Don’t be slave of others when Allah has created you free.
