PhD ABD here.
ABD = all but dissertation... at this point I do not think I will finish mine though my wife is making the process look easy and should have her PhD completed this summer.
I wasted my first attempt at a 4 yr degree and ended up with two AS degrees in Computer Science and Electrical Engineering. I built my career to a pretty high level with those and after a couple of decades figured I should make my education catch up to my titles. I completed a BS in Business Management then an MBA a couple of years later. The MBA opened a lot of doors for me and allowed me to escape the traditional job. I really enjoyed the grad school process and that prompted me into the PhD program. After a couple of years, there were too many conflicts with my occupation and life in general so I stepped away before I finished. Also, it gets kind of expensive when you have a family of four and are paying for school for all four... 3 in college and 1 in private school.
