As I read the list, I find myself measuring my blessing. Actually, I find myself questioning why I am not getting more. With that mindset, true blessing will never come. The problem is in the focus. Reading that list causes me to focus on what I should praise God for, rather than why.
The Psalmist gets it right in verse 1. It is the man that fears the Lord and delights in his commandments that finds blessing. In fact, he will find each of those traits present in his life, even if they be in seemingly small measure.
