Try this instead of a general counting-your-blessings exercise, which is easy to say and easy to do badly.
Take one ordinary thing from the last week and write down the specific facts of it. Not “my family”, but the actual conversation. Not “provision”, but the exact way the money or the help arrived. Specificity is what makes gratitude real, because your mind cannot argue with a detail.
Then keep the list. The psalmist did not write one poem about remembering and then move on; he kept returning to it, because he knew his own memory. You will forget again by next month, and that is less a failure of character than a fact about being human. The list is a way of arguing with your forgetfulness, and it works better than trying harder.
