Finding Contentment?

I have been criticized more than once for never being content with my lot in life. Never enjoying what I have and always asking for more when I get what I originally stated I wanted. I don't disagree with these statements, but I also don't know that it is entirely negative.

I found an interesting blog post that outlined many of my feelings on the matter:

"Contentment with continued growth is a difficult balance to strike; so much so that as soon as my life slows down and I find myself not worried or concerned about things, I have a tendency to take on a new responsibility. A new pet or hobby, is a good example. I think it’s a reaction of feeling as though since I’m not struggling, I am in danger of becoming stagnant."

This is my constant struggle and I think my resolution for the rest of 2011 and all of 2012 will be to strive to be more content without getting anxious that I am not moving forward at breakneck speeds.
