"Fortitude is a basis for cheerfulness. Fortitude induces you to face the inevitable sorrows of life and, above all, death itself, in the service of God with courage and patience. You will look to the sufferings of Christ for inspiration. You will look to the happiness of Heaven with a heart full of hope, and you will count even the greatest sufferings as a small price to pay for that reward. Therefore, try to overcome cowardice, self-pity, and lack of confidence in the goodness of God --faults that prevent you from being cheerful. As a result of these faults, you may find yourself constantly grumbling against God and everybody around you because of the sufferings you have to endure.”
The Hidden Power of Kindness, Father Lovasik
