The next time you're selling or buying something on eBay, think about giving a portion of your sale or purchase to the charity of your choice. eBay's Giving Works platform makes it easy to support causes that are international, national and even local, and that help animals, the environment and other worthy causes. It's an easy way to give and support at the same time since the charities will highlight sellers who support them and buyers can feel good knowing they found what they need and are giving to a good cause, too.

It's easy to save money and stop paper waste at home or in the office with these simple tips. First, check your computer printing defaults and set the printer to automatically print double-sided. This will cut your usage in half right away. Only print the pages you need: Instead of printing out 50 pages of a document when you need, say, six, take the time to print the exact ones you need. Finally, instead of printing out mailing labels, print your addresses directly onto the envelopes. Many printers are designed to hold envelopes, so you can save time and money by running envelopes through the printer.

This month, my new magazine, Naturally, Danny Seo, hits newsstands across America. The mantra for the magazine is simple: It's where style meets sustainability. In the launch issue, we trek to Africa on a fragrance journey, share my Top 12 all-star juicing and smoothie recipes, and learn how to upcycle kids' toys into beautiful new home crafts. If you love my tips in Do Just One Thing, I think you'll love my new magazine, too. I would love to hear from you: Tweet me @dannyseomag, and thank you for the continued support.
