I have recently bought a Canon550D twin lens kit. I am on a budget because I am really trying hard to get a canon for hubby.

What I really would like to know is what will I be needing most? I want to do so many diffrent kinds of things until I find my niche & of course that will probably change. What should I be looking at as my next out lay?
I know this is a very broad question & I have looked though the site. If someone could generalize that would be great.

Thank you
