After the first initial buzz of having a camera again, (I gave up for about 10 years pre 2003 when I got my first Digital Camera) I joined a site called
Fujimugs. It was a good way to get motivated, especially through the long dark nights. It also 'forced' me to try stuff I may not have thought of doing because I wanted to be involved and learn.
It was initially set as a photo challenge site for owners of Fuji cameras, hence the name. There are now two sections, the Main section for Fuji cameras, and an Open section for any other brand. There is a challenge set every couple of weeks, by the winner of Main section of the previous challenge. You have the time between the challenge being announced and the closing date to take a pic for whatever the subject of the challenge is. No appropriate pics you may have hiding on your HD.

There is then a weekend of voting and commenting, all anonymously, so hopefully the images will be the only thing voted upon, rather than voting for 'friends', and then the results announced on a Monday night. If you have a Fuji camera you can enter a different pic in each section.
I always say to people that if they can't think of anything to take a picture of go to Fujimugs as they are approaching 200 challenges, and so there are that many ideas for a subject for a picture. The challenges started in 2003, and there have been some excellent pics over the years with gear that is nowhere near advanced to what we have now. So you can't use the quality of your gear as an excuse.
I haven't entered a challenge for awhile, but have enjoyed entering the challenges over the years, and learnt a lot doing it, both from how othera interpretated the challnge, and the comments I received. I've won a couple, but have come last more often.
Of course that may not help if you are 'done' with photography, but if you are just lacking inspiration, and a bit of motivation, it is worth a look.
