A self-made millionaire mum describes how she uses a digital timer to keep herself focused on getting work done during certain times of the day. As a "work"-from-home mum of a two-year-old, I find it necessary to structure my writing and blogging time according to her schedule and push to GET IT DONE.

Few skills are as useful for a Friday afternoon as the rewarding power nap. The Ririan Project introduces 10 benefits to power napping and details four styles of power nap: nano nap (10 to 20 seconds), micro nap (two to five minutes), mini nap (five to 20 minutes), lazy man's nap (50 to 90 minutes) and the traditional power nap (exactly 20 minutes).

Windows only: Shareware application ShrinkMyTunes promises to fit anywhere from two to four times more music on your iPod by shrinking your MP3s while retaining most of their quality. Hot on the heels of Apple's announcement of the enticing yet light-on-storage iPod touch, this type of application could come in particularly handy. We hardly ever post shareware here on Lifehacker, but if ShinkMyTunes does work as well as they claim it does (or even as well as Wired's review suggests), it's an application that may be worth the rather hefty $40 price tag for some music lovers with small storage capacities. (Then again, who among us hasn't been working to increase the quality of their MP3 library?) ShrinkMyTunes is currently Windows only, costs a whopping $40 (but offers a 14-day money back guarantee). Let's hear your thoughts—including how you fit as much content as you can on your MP3 player—in the comments.
