With used dSLR prices dropping especially for the rebel and rebel xt (probably due to the xti?)....it seems like there's a lot of new people finally stepping into the SLR world
myself included, my "new" rebel should be here soon ('bout a week) along with a used 50mm 1.8 to break it in 
Anyway, I know there are a lot of FAQ's and all that up top of each forum....but if you could "knew what you know now"...
anything come to mind right away for the new folks? any bad habits you wish you didn't start? any good ones you started late and wish you started sooner?
c'mon, let's hear a few general newb tips 
edit, I'll start...since I am not new to photography, and wish I knew a few things starting out...
I really wish I knew the basics (rule of thirds) before I started shooting back in the day. Back when I very first started I had no idea about photography but thought I did and never cared to read and educate myself about "the basics" ... as a result I find myself regretting not knowing about them from time to time...because I know everything I shot could have looked so much better...
