I know exactly what you mean. We thought it would only take this weekend to strip the wallpaper downstairs. Wrong. Still have another few days left with stripping, then wash the damn walls, then prime, then paint. Ugh. 
Man do I have some painting tips for ya.
1) Don't buy paint at Walmart
2) Only buy paint where it's electronically matched and mixed.
3) Only buy a quart at first and then buy the rest once you've tossed it up on a wall and like the way it looks (I've got a few gallons of ugly paints sitting in the garage)
4) Sherwin Williams paint is awesome. You can get their Premium satin finish paints for around $22 a gallon (if you haggle).
5) Power rollers will rock your damned world.
6) Buy lots of painter's tape. You might have a good hand but there's no way in hell you'll be able to get a straighter line than with tape.
7) Buy me beer (Just because).
