How do you cope with post vacation blues?

More vacations!

Increasing productivity day by day till I reach the productivity I had before vacation.

Working on micro-incentives everyday.

need increase your activity step by step)

Plan the next one ;) But for real, if you're dealing with post-vacation blues than take it easy, step by step.

The usual advice is to ease in, ease out. Take it easy a few last days before the vacation and a few days after. My real advice though may be a bit controversial. Make your work look more like vacation and make your vacation look like work. For me, vacation is just an option to do some work from a beautiful place. Hald day work, half-day exploration. It is probably just me though.
