I'm sorry about the presentation snafu. Don't beat yourself too much over it, though. These things happen. Plus, if you're even just a little bit like me, your brain just refuses to file stress-inducing info, such as deadlines. The way I did it (in uni and actually still do for work stuff) is having a nice big calendar right next to my work station/computer. I write down deadlines as soon as I have them, so that they stare nicely at me, since my brain refuses to store such info.

Is it worth it?

IT IS. I ♥ voiceposts.
