if it is raining you should perhaps be looking for shots outdoors in the rain!
check your equipment
clean your digital camera sensor
ideally need to take a photo of a spotless subject such as the blue sky wth camera set to f/16 so you can see the dust on the sensor
clean your lenses and filters
microadjust your autofocus
not needed for mirrorless cameras, but all dSLRs which have a microadjustment option should be calibrated to ensure you are getting the sharpest possible photos
manage all those photos
post-process photos
resize and upload to web
most importantly back them up in at least 2 different places

the subject does not need to be a person, here are some other ideas:
