Since 2010 I've been keeping a diary on my computer. Last week I got around to printing the whole thing out. Three years (and counting) of personal journal entries are now printed in 16-point Courier on 3-hole punch paper, and they fill three 2-inch ring binders. Somehow it's comforting to have my journals in physical form, but it also helps me to feel my writing is going somewhere.
I'm making it a point to print out what I write, rather than just leaving it on the computer, because I think having it in tangible form helps to keep the process going.
