During times of intense work (such as the start of a new academic year), I sometimes fall back into old habits and move away from Evernote. I have to remind myself that Evernote doesn't really care if the note is tagged or saved to the right folder. It's always better to have something in Evernote than simply sitting on my desk as a hand-written note or handout.
So....even if you're an "Evernote Slacker" like I've been in the past few weeks, don't worry - just keep sending everything you want to remember to Evernote.
