I start a project and come to some understanding on how to do something very efficiently (after getting halfway through the project) and then totally forget when I start a similar project. Case in point: Painting... After starting and gaining little ground cause I am having to do second and third coats it dawns on me that I figured out how to avoid this last time I painted... Thicker paint!
So here is a little tip that will save you TONS of time while painting. Use a lot of paint. Slap it on thick. Don't try to spread it out too much. You will be amazed when you get the work done in half the time. Also, do all the fiddly bits first. The corners, the trim, everywhere your roller won't get to. It's a lot easier doing the hard stuff first. You get real tired of painting when you do the rolling first then realize you have to do all the fiddly bits. Hope my tips help. Oh yhea, I painted the bedroom this weekend (after having it sit unfinished for 1 1/2 years).
