This is another cool way to play come as you are.  It's not any easier, but it's pretty fun to play. For the part where it goes from 2 to 5, use your index finger for the 2 and your pinky for the 5.For the part where it goes from zero to seven, while you are playing the zero, move you're hand up to the seventh fret.
