Or even if you can teleport at (or perhaps just below) the speed of light; I would still offer to explore our solar system.  It would take 4 years to teleport to our nearest star, which would be very boring plus you'd starve to death on the way there (unless you experience length contaction/time dilation - which means you could explore the entire universe in a lifetime which would be awesome - problem is when you got back to earth, potentially millions of years would have passed.
