It's not a problem, you just have to make it work for you. I too don't have the longest fingers, they are kinda short. But my hand is wide so I do have a pretty good reach, better now then when I started. Victor Wooten is one of the best all time and his hands/fingers are kinda small (I know I shook hands with him).
I heard some one say once don't know who. "Do the best YOU can with what YOU got".
