Try curbing your unnecessary curiosity! We are such curious creatures, and it's a good thing, otherwise we would not have some of our great inventions or some of the things that make life a bit easier for us. There is also a wondrous and beautiful world to explore for which we can glorify and thank God. However, there are times when we should not be so curious, especially when what we are interested in is absolutely none of our business. When our thoughts are always centered on others in this manner, we start to lose the concern for our own lives, the self-knowledge that we need to work to change our lives. It can also be the beginning of a tendency to gossip...a real killer in the spiritual life.
It is so easy to do because we are such weak, wounded people. If we can "catch ourselves in the act”, and stop before we say anything, it's a good thing. It is also a great penance, saying "no" to what we want to do, because it is a hidden penance...no one knows about it but myself and our Heavenly Father.
We can try to keep our minds recollected and, as St. Paul tells us in Philippians: "Fill your minds with everything that is true, noble, good and pure, everything that we love and honor, and everything that can be thought virtuous or worthy of praise...Then the God of peace will be with you."
