Back up your files.

Last Friday my hard drive died.  It's completely gone and I lost all of my files and some programs I had obtained...  I never thought it was necessary, but trust me, it really sucks when you loose every thing.  There are hundreds of pictures I'll never get back, and thing I never knew I needed until I didn't have them anymore.  Back up your files, it's a lesson I learned the hard way, but one I won't soon forget.  My boyfriend is so awsome and let me borrow his laptop for a few days, but I can't wait to have mine back.
