Winter Blues

Is it just me, or does everyone find it difficult to keep actively taking photographs throughout the dark, damp winter months in England? When it snows, or when we are hit by a severe frost, we get inspired to grab our photo kit and head for the (scenic) hills. However, when it is raining, inertia takes hold.
I have been using the time to try to manage my images. Has anyone yet found the perfect image filing system? Adobe Lightroom and Bridge are both almost there but what of the actual folder structure on th hard drive? Should raw files live with the final images?
I have yet to find the perfect solution, when I do, I’ll be sure to share it here.
