Cutting down and clearing out

The new year approaches, and now is a logical time for me to get rid of junk/crap/clutter/stuff. As I type I have a group of boxes in my living room labeled donate, not sure, cords, etc. I have yet to be successful in this task.

I do not want to go the minimalist route, but I wish to drastically cut down and live more lightly. Please share with me your favorite clutter removal and life lightening tips.
