The stain is a pain.

When staining three rooms' worth of woodwork - windows, closet doors, entry doors, trim, baseboards - it is important to remember a few things:

• Foremost, have good tunes to listen to - this helps to alleviate the mind-numbing boredom that can otherwise easily set in.
• Wear crappy clothes - just put the same old things on day after day after day after day.
• Have plenty of rags and rubber gloves. The rags should not be confused with the crappy clothes that you are wearing endlessly - they will be the rags you use on your next project...should you be wacky enough to repeat this. 
• Have plenty of ventilation - wide open windows, the more the better. That warning on the can? They're not kidding.
• Allow plenty of time - something that feels akin to practically forever.
