I've fallen into a slump as of late. Pretty much stagnant in terms of improvement, so I've set up a couple of things I need to work on.
1) Use flash all the time -- master flash photography (oh snap)
2) Use the 18-55mm lens more (see if i like 18-50 range)
3) Do some macro photography before I sell my 90mm f/2.8
4) ???

So much for the 18-55mm ef-S. I wanted to keep it because its pretty sharp and nice, but I guess I'll just have to replace it.
Sold it today.
