Once you start working, you're expected to do that for the rest of your life. So don't be too eager to jump into a career as soon as you can.
Also, you can only desire based on what you know. Most people graduate from school having gone through one giant funnel that took them to that point, so the direction you're facing now might be more a reflection of that framework than yourself. Take some time to step outside traditionally supported structures and do something completely different.
Hitchhike to Alaska, start a band and go on tour, ride a bicycle as far as you can, start a traveling puppet show. Do whatever — but make it really uncomfortable, and make it count.
