Am I Appreciative?

I decided to look it up:

ap·pre·ci·a·tion [uh-pree-shee-ey-shuhn] –noun

1. gratitude; thankful recognition: They showed their appreciation by giving him a gold watch.
2. the act of estimating the qualities of things and giving them their proper value.
3. clear perception or recognition, esp. of aesthetic quality: a course in art appreciation.
4. an increase or rise in the value of property, goods, etc.
5. critical notice; evaluation; opinion, as of a situation, person, etc.
6. a critique or written evaluation, esp. when favorable.

I was surpised to find all of the materialistic references in the definitions of appreciation (as bolded above).

I guess I'm a little angry with myself, that I appreciate things after they have already taken place, and after I have not "lived in the moment" so to speak. Why is that? How come I can't stop to be thankful that my son can walk and has two feet to put his shoes on, rather than getting upset that I can't find his shoes. How come I get down on myself about my work situation, rather than being thankful that I have a good-paying job that allows me to see my kids more than the average working mother. How come I worry so much about money, rather than being appreciative at the fact that my husband and I are healthy enough to work and enjoy what we do?

How do I ingrain that into my head to where it becomes second-nature, rather than just wishing I could be that way?
