Once a year is not often enough.

Woe, to you, O my darkened soul!
Your life is stained by depravity and laziness;
your folly makes you shun all thought of death.
How complacent you remain!
How can you flee the awesome thought of Judgment Day?
When will you change your way of life?
On that day your sins will rise against you.
What will your answer be then?
Your acts will condemn you; your deeds will expose you.
The time is at hand, O my soul.
Turn to the good and loving Savior!
Beg Him to forgive your malice and weakness, as you cry in faith:
“I have sinned, O Lord, I have sinned against You,
but I know Your love for all mankind.//
O good Shepherd, call me to enjoy Your lasting presence on Your right hand!”
