A mass of good resolutions, I think, are apt to end up in disappointment and to make one depressed. Also direct fault-uprooting: it makes one concentrate too much on self and that can be so depressing. The only resolution I have ever found works is: "Whenever I want to think of myself, I will think of God."
Now, this does not mean, "I will make a long meditation on God," but just some short sharp answer, so to speak, to my thought of self, in God. For example:
"I am lonely, misunderstood, etc." The loneliness of Christ at his trial; the misunderstanding even of his closest friends.
"I have made a fool of myself."
Christ mocked — he felt it; he put the mocking first in foretelling his Passion — 'The Son of Man shall be mocked, etc.' — made a fool of, before all whom he loved.
"I can't go on, unhelped."
Christ couldn't. He couldn't carry the cross without help; he was grateful for human sympathy — Mary Magdalene — his words on that occasion — other examples as they suggest themselves — just pictures that flash through the mind. This practice becomes a habit and it is the habit which has saved me from despair! ...
Different people have different approaches to Christ. He has become all things — infant, child, man — so that we all can approach him in the way easiest for us. The best is to use that way to our heart's content, and not to trouble about any other.
