Well, what degree have you enrolled in? Computing? Hair dressing? Tiddly winks? Shaving?
If its a degree that has you doing some programming, maths and software develpment then 100% it will be worth it. If its something completely unrelated and - quite frankly - useless towards the goal of developing software then you need to switch to a more relevent degree.
In the end, its a decision that only you can make. Some swear by having a degree, is a right to a job or that "the paper" is for wiping their bum clean. I took mine out of fear of the future and peer pressure, but in the end, I felt it was both a personal accomplishment I am proud of and yet it was also holding me back from allowing me to focus on exactly what I wanted to do. Did I get a job out of it? No, but it did teach me how become a better programmer, and it allowed me to become part of the field in some small way - helping other students when the chips were down, some in very unfortunate situations.
Consider what all have said here, and make sure you have thought it through thoroughly before throwing in the towel.
