Gratitude is certainly a virtuous quality to cultivate. However, I noticed that there are many items on your list that strictly material and ego-related in nature. I don't suppose you're Buddhist so I don't expect you to have that level of understanding, but I do believe that some Buddhist teachings could potentially be of service here.

One teaching that may be of benefit is the Three Marks of Existence: http://en.wikipedia.org/wiki/Three_marks_of_existence

Essentially, this teaching states that (1) all conditioned things (which is everything on your lists) are impermanent. Thus, (2) they are unsatisfactory, unable to bring a lasting happiness. The final aspect to this teaching is that (3) nothing in existence is an attribute of one's "self." The perceptions we experience, our thoughts, feelings, physical and psychological characteristics, our actions and life experiences- none of these are attributes of a self, but rather a conglomeration of impersonal conditioned phenomena.

Another teaching that may be helpful is the doctrine of Clinging/Attachment/Grasping: http://en.wikipedia.org/wiki/Up%C4%81d%C4%81na

This teaching states that clinging, craving, and attachment to material things, one's views, beliefs, and sense of self, sensual desires, ect, is the main cause of suffering in one's life.

The reason why I believe these teachings may be of service is because I can see how having appreciation for certain perceived qualities or personal characteristics and pleasant phenomena can lead to attachment. Understanding and accepting that nothing is permanent, that conditioned phenomena (the entirety of our experience of physical reality) is ultimately unsatisfactory, and that none of it is actually "you" may help one to release possible attachments to these material and impermanent things and thus eliminate the suffering that would be caused by the eventual cessation of these objects of attachment.
