DUH! Copy the thank you cards you write during the interview process --- it may be a long one!

I submitted my resume for a position back in April (it's now June). Since then, I've had 6 individual interviews and today had a panel interview with 5 people ---- 3 of whom I've interviewed with before. I'm writing my thank you notes tonight and realizing how great it would be if I had copied my notes from before so I don't sound EXACTLY the same (I many ways are there to end a thank you note -- I WANT AN OFFER AND HERE'S WHY!, right?). 

So, even if you think it might be a short process, copy those notes so you have them!
