Furthermore, having money to buy unnecessary stuff for your hobbies is not the metric to go by. The more important metric is about what you're able to save. Important questions are:
* Are you saving enough money to ensure a comfortable retirement?
* Are you saving enough money to buy your children (assuming you have/will have them) a decent education?
* Are you saving enough money to cover medical expenses later in life?
* Are you able to set aside an emergency fund?
If the answer to any of those questions is "no", then you should probably be concerned.
