I'd like to share a couple tips with you to help ease some of the organizing burden. First, when you put a tab on the hanging folder, make sure you put it on the front edge instead of the back edge. Doing this will ease your filing process a bit by allowing you to grab the tab and insert the paper you're filing into the front of the file. This will keep your most current documents in front and will save a bit of motion when filing a lot of papers. Second, don't feel like you have to catch up on all your filing in one attempt.
Progress is the important thing here.
If you have a few spare moments, grab a small stack of papers and file them. If you use your available time in this manner, you'll quickly see progress and will feel a tremendous sense of accomplishment as your paper piles start to diminish. Third, make a filing goal and stick with it. If you set a goal that is attainable, you can gradually work toward accomplishing that goal. Better yet, write down the goal on a Post-it note and put it on your computer monitor so you can be regularly reminded of the goal you've set.
