Re: Motivation Needed

Jolt cola.
Crunchy foods and snacks.
Avoid dairy.
Don't eat a really heavy dinner, but do drink lots of water.
A full ipod, set for just the instrumental tracks, so you can listen to the dialog you're cutting.
Hourly walk-around break, at least five minutes.
Set the air conditioning to slightly colder.
Don't just sit and munch the treats, promise yourself you can have one fun size candy after x number of edits are done.

And work smart, not hard; use templates and re-cycle effects setups and graphics beds so that you don't have to re-invent the wheel every time. Systematize.
Work those jkl keys and play everything faster than normal but still audible to find edit points.
Don't forget to save often so you have a current backup. Stuff starts to break down after hours more often than during the day.

My edit bay aeron chair knockoff has a Homemedics shiatsu back massager cushion on it, this is the greatest thing since the 3-way color corrector.
