In my opinion (which can often be wrong haha) you are both right and wrong. Right that you should focus on being happy with what you have -- but you are still comparing it against other people :)

My biggest steps to being happy was realising that what I had, however little, was actually really important to me -- therefor I stopped giving two shits about how other people viewed me or how I viewed myself in the social hierarchy!

Hard to do, but alas, Inward thinking is the right path I think :) You solve that problem and then things will come to you abunantly.
