Simplest words, you can't. Traveling at the speed of light would take infinite energy and you'd weight an infinite amount.
If you could for you the trip would be instant because at the speed of light there'd be no time passing, and for an external observer the trip would take 10 to 20 hours or so, depending of course where earth and pluto were in their respective orbits.
The faster you go, the slower time passes for you.
