Quote: The values I developed were instrumental in gaining a competitive advantage. — John Collison (1990-) Irish entrepreneur

Lord, make me an instrument of your peace.
Where there is hatred, let me sow love,
Where there is injury, pardon,
Where there is doubt, faith,
Where there is despair, hope,
Where there is darkness, light,
And where there is sadness, joy.
Divine Master, grant that I may not so much seek to be consoled as to console;
To be understood as to understand;
To be loved as to love;
For it is in giving that we receive,
It is in pardoning that we are pardoned;
And it is in dying that we are born to eternal life.
— Saint Francis of Assisi [born Giovanni Francesco di Bernardone] (1181-1226) Founder of the Franciscan Order
