John Bosco quotes:

We do not go to Holy Communion because we are good; we go to become good.

Whatever you do, think of the Glory of God as your main goal.

Only God knows the good that can come about by reading one good Catholic book.

Fly from bad companions as from the bite of a poisonous snake.

Run, jump, shout, but do not sin.

Ask your angel to console and assist you in your last moments.

Enjoy yourself as much as you like - if only you keep from sin.

The power of evil men lives on the cowardice of the good.

Health is God's great gift, and we must spend it entirely for Him. Our eyes should see only for God, our feet walk only for Him, our hands labor for Him alone; in short, our entire body should serve God while we still have the time. Then, when He shall take our health and we shall near our last day, our conscience will not reproach us for having misused it.

Do not try to excuse your faults; try to correct them

Be good. This will make your angel happy. When sorrows and misfortunes, physical or spiritual, afflict you, turn to your guardian angel with strong trust and he will help you.

Be ever more convinced that your guardian angel is really present, that he is ever at your side. St. Frances of Rome always saw him standing before her, his arms clasped at his breast, his eyes uplifted to Heaven; but at the slightest failing, he would cover his face as if in shame, and at times, turn his back to her.

The principle trap that the devil sets for young people is idleness.
