This is old advice but timeless:
1. Thank God. Often and always. Thank him carefully and wonderingly for your continuing privileges and for every experience of his goodness. Thankfulness is a soil in which pride does not easily grow.
2. Take care about confession of your sins. As time passes the habit of being critical about people and things grows more than each of us realize. …[He then gently commends the practice of sacramental confession].
3. Be ready to accept humiliations. They can hurt terribly but they can help to keep you humble. [Whether trivial or big, accept them he says.] All these can be so many chances to be a little nearer to our Lord. There is nothing to fear, if you are near to the Lord and in his hands.
4. Do not worry about status. There is only one status that Our Lord bids us be concerned with, and that is our proximity to Him. “If a man serve me, let him follow me, and where I am there also shall my servant be”. (John 12:26) That is our status; to be near our Lord wherever He may ask us to go with him.
5. Use your sense of humour. Laugh at things, laugh at the absurdities of life, laugh at yourself.
