I saved every penny I had for 2 years working as a Software Engineer. During the trip I freelanced a little, managed a hostel for 5 months, and wound up with the balance on my credit card.

I've just finished paying off my Credit Card, so have started saving for the next one. I work full time and am just about to start my 2nd and 3rd concurrent jobs.
