f you want to go back to the spot you left off when you open a Word document, press Shift+F5. Word will take you back to the last place your cursor was in the document.
If you use a free blogging service like Blogger.com, you do not have a database of your posts in case of a failure at the site. But you can backup your blog for free at Blogbackupr.com. You just need the URL of your blog and an e-mail to which you want your password sent. If you ever need to restore a post (if you accidentally deleted it, for instance), you can retrieve from blogbackupr.com.
Organize your photos by the date they were taken in a chronological hierarchy of folders for years, months and days (e.g. 2008 > 02 > 02 for photos taken on February 2nd, 2008). Create logs with brief descriptions of each date for quick references (e.g. "2008.02.02 - Groundhog's Day at Punxsutawney, PA"). I like to keep separate monthly logs (simple text files under the each month's folder) and yearly logs with highlights (under each year's folder) but experiment to see what works best for you.
Put all your mp3s in a single music folder and set the view settings to list files by name (or details). Name each MP3 file using a format such as "ARTIST - TITLE.mp3" (e.g. "Coldplay - Clocks.mp3"). To organize songs by album as well then do something like "ARTIST - ALBUM - TRACK - TITLE.mp3" (e.g. "Justin Timberlake - Justified - 05 - Cry Me a River.mp3"). Keep filenames readable/consistent and your songs will be listed alphabetically/chronologically by artist, album, track # and song title.
