While most of the time these things are about our daily life, every once in a while something will get a hold of our heart that is good. The psalmist here is saying my heart is full of a good matter. Maybe it was surprising that with everything that was going on, he would begin to dwell on a good matter.
To indite means there is something in his heart that has reached a place that it can no longer stay down in his heart, but it must come up. The reference is that of a fountain, as water flows up from the depths and eventually burst out the top, so is this good matter that the psalmist has in his heart.
I would challenge every reader that is going through a down time, a discouraging moment, or maybe just having a bad day....to start inditing a good matter. Begin to set your heart on some good things that God has done for you. Let that good thing begin to rise up from your heart until you can't contain it anymore. Let that good matter burst from your lips in a form of praise unto God. How long has it been since you have indited a good matter.
You've thought on a lot of things, but now is time to dwell on a good matter. Cleanse yourself of negative thoughts and begin to indite a good matter. Don't let your situation get the best of you, rise above it by inditing a good matter.
