There is a lot of good financial advice in this thread, so no need to rehash that here, rather focus on the personal habit side of things.
Saving is a choice. There are obviously degrees to what an individual person can and can't do, but everyone can do something - it's a choice, a decision made and kept.
It's up to the individual what kind of lifestyle they want to live - and you might be surprised how well you can live by disciplining yourself to live below (I would say "within") your means in order to save above your means. And that doesn't mean that you have to deprive yourself of a good quality of life in so doing. I would argue however, in evaluating what is a good quality of life there's a big difference between a need and a want - you just have to condition yourself to be content living by and committing to a budget.
For example, set some ambitious goals for yourself. Pick something and do it - maybe you want to eventually save 25%, live off of 50%, pay taxes 25%. Or, maybe you want to eventually save 25%, give 25%, pay taxes 25%, live off of 25% ... or whatever it is that you target as a goal (goals can obviously change).
It's a personal choice.
You do that for 20-30 years while you are young and you will be glad you committed to that structure and discipline in your life as you get older - and not just for the obvious financial reasons.
