In many developing nations you can save a lot even from a $1k salary. If not, dedicate some time to freelancing, either locally or via elance/odesk. Shoot let's say for $40k per hour and do 2-3 hours per evening of that, plus some time on weekends. 20 hours = $400 per week, $1600 per month additional. Do that for a year and you will have money to live on saved funds for 1,5 years.

Depending on which country you live in, taxes can be a real pain and will only leave you with a small bit of your salary. Not to mention transportation could eat up a lot your otherwise "free time" in the evenings. :(

I do agree that freelancing would definitely give some nice extra income but only if you're disciplined enough to find time for it.
