Day 17 (The Third Monday of Lent, also St. Matthias this year): Only fill your kettle with as much water as you need.
This is another one more suited to the UK; I'm not sure how many Americans regularly use a tea kettle. But it's good advice anyway; watch what you are using as you prepare your food and drink. can you use less water, less gas, less whatever?
I don't drink much tea at all, so I use a tea kettle perhaps once or twice a month. I can't think of any other ideas at the moment. Anyone?
Look upon the heart-felt desires of your humble servants, Almighty God, and stretch forth the right hand of your majesty to be our defense against all our enemies; through Jesus Christ our Lord, who lives and reigns with you and the Holy Spirit, one God, for ever and ever. Amen.
