Honestly it's a non-question.
There are a lot of variables;
1> To what extent is money your main motivator. Do you like curing children of diseases, hugging puppies or beating up drunkards? Or do you want to sit in an expensive club, pouring vintage champagne over your own personal Swedish beach volleyball team?
2> To what extent do you NEED the money. Do you have a huge mortgage? Do you have lots of dependants? Are you free as a bird with cheap taste? Do you have a habit to feed...?
3> Where do you live? Working and living in the city, it seems insane to me that anyone can survive on 25k in London - I live alone and spend everything I earn. And I earn a heck of a lot more than that. Yet in parts of the north of England, this salary could be enough to live comfortably and support a family. This country is ludicrously disparate.
4> How hard, and for how long do you want to work? If you work at an investment bank, as a new grad it is highly likely (in some roles) that you will earn much less on an hourly basis than a checkout assistant or even a benefit claimant. Yet they will have a chance to have a social life, and are far less likely to die of stress or a cocaine overdose at the age of 30.
A good salary is a meaningless concept really - you need to look at life as a package. Are you happy? Then who gives a toss what you earn.
