Just off the top of my head, I can think of the following (in no particular order of preference):
1. Try more wines from other regions than just Baden and the Pfalz
2. Try more Weißburgunder - it is an underrated and beautiful thing
3. Try more wines from the best, and nearest, local producers (e.g. Schneider in Weil, Ziereisen from Efringen, Blankenhorn from Schliengen, Schlossgut Istein..)
4. Try more "international" varietals grown increasingly in Germany, such as Chard, Sauv Blanc, Cab Sauv - but don't overdo it.
5. Continue my quest for decent but inexpensive Spätburgunder
