Lingering bitter cold with grey overcast skies can really put a damper on photographic aspirations (especially if you enjoy shooting lush, vivid landscapes). The solution? Try shooting macros!
If you can stand the cold, then there are lots of wonderful outdoor subjects that are likely very close by and just begging to have your camera pointed at them – icicles, frost and snowflakes, just to name a few. The image at the top of this post is from an herb garden on my front porch.
If you'd rather avoid the cold entirely, setting up a small indoor macro studio doesn't require much space. In fact, you could easily use your dining room table or similar [even smaller] surface. And there are tons of things in your home that would work well as macro subjects – spices (like sea salt, peppercorns, etc.), toys and flowers are only a few examples. And as Bryan has noted before, buying flowers will likely make your wife or significant other very happy. By the way, an off-camera flash paired with a small softbox makes an excellent tool for macro photography.
Want a real challenge? Try your hand at shooting jewelry. With gemstones and curved, metallic, mirrored surfaces, jewelry can be an especially challenging subject to illuminate attractively (Hint: using several well-placed white (or other colored) reflectors can help accentuate jewelry's appearance).
Want to take your macros a step further? Try focus stacking (my technique can be found midway down the post).
Shooting macros can be a fun and fulfilling activity when other types of photography are less enjoyable or satisfying. So be creative and have fun with small, everyday things!
