Is there a faster method to solve a rubik's cube, or is this the fastest there is?

I recommend the Fridrich F2L method, it is the fastest method overall. This method may turn out to be hard and confusing at first, but this is a thinking method. The more and harder you think, the faster and better at this method you will become. If you do not like thinking and stuff, then you can use the keyhole method, it doesn't require a lot of thinking and is pretty quick. But yes, learn OLL and PLL algorithms, it's worth it.
