While I shoot professionally, mainly corporate and events plus model portfolios and the odd wedding I also try to have a walk around Lincoln at least a couple of times a week.
Its a very photogenic little city.
I often have a number of projects on the go, my main ones are drinks and doors at the moment, plus people on the on the phone, but I also have a lamp post and signs project. Simple little projects like this give you a focus when you are lacking in direction.
Its an easy thing to do and can lead to some interesting future ideas and keeps your interest when you need some inspiration.
