This actually hasn't to do with mixing, but I'd say a very important point is the ability to discard stuff. I think it's always good to have a healthy rate of wastage. If you discard too many ideas, it is an indicator that you should develop further in the current direction, if you discard too few ideas, you probably should try another direction.
Many good ideas here. I agree with this one especially. As Austere pointed out, mothballing is a decent option, too. There may be a good germ of an idea that does not sustain itself over 6 minutes, but may make a good 1-2 minute transitional section or added layer to a different piece much further down the road. Another problem with not critically self-editing one's output is that you make the listener work too hard to find the good stuff.
