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

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

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.

Run, jump, shout, but do not sin.

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.

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

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

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