Efficiency....what methods do you use to make a job go easier?

I have found that cleaning up here and there as I go and putting away tools that I am done with as I go is a big help to me. When I spend all day in the garage cutting, fabbing and welding (or whatever), I can have a pretty bad mess at the end of the day. A mess that can take 45 minutes to clean up. But if I do it a bit here and there, the cleanup is a lot less at the end of the day. And at the end of the day, when you are tired, would you rather have a 20 minute cleanup or a 45 minute cleanup staring you in the face?
