I think this is an issue in itself. We all compare ourselves to others.
I'd say up until the start of this year, I was in a relatively good "life position" (definitely just made that up). Had a long term partner, had savings, were going to buy a house etc etc. Then the relationship finished, had to use my savings to clear some new found debt, and now find myself in a position where I was around 10 years ago. However I am a lot happier for it.
Far too easy to think life is as simple as - grow up, buy house, marry, have kids, retire, the end. Not going to be like that for everybody, everyone has there own unique set of circumstances.
