Graduate Life - it's not just a job, it's an indenture. This is particularly true of Ph.D. programs - doctorates generally don't help much in industry and the academic market for them is very tight. Still, if your goals require an advanced degree, then you should go for it, but such a process shouldn't be undertaken lightly.
Most people go to graduate school to qualify for better jobs.
A graduate degree can also lead you to more interesting and rewarding work. Most of all, graduate degrees are a must for someone planning on doing research or university teaching. Having a graduate degree can be rewarding when negotiating a salary. So while it can be rewarding going to graduate school, it is not something to jump at.
