We should not want to practice many exercises at the same time and all of a sudden. The enemy often tries to make us attempt and start many projects so that we will be overwhelmed with too many tasks, and therefore achieve nothing and leave everything unfinished. Sometimes he even suggests the wish to undertake some excellent work that he foresees we will never accomplish. This is to distract us from the prosecution of some less excellent work that we would have easily completed. He does not care how many plans and beginnings we make, provided nothing is finished.

--St. Francis de Sales
