another good thing about having a degree is it gives you more options later in life. If you have an undergrad degree in anything its easier to move to another field, as many universities let you do a masters (or grad cert/grad diploma) without an undergrad in the same field.
this was another rationalization for sticking with my degree and straight after i went and did a g dip in another field, which was way more interesting and enjoyable. I also knew i could quit it any time if i got bored of it.
you should also not discount doing a course part time through
