In a post I link to a web site that I recommend. I myself had not visited that website for awhile and I saw that Dr Goldhammer has a cookbook.
Immediately I go to "Favorites", click on "Amazon", and buy the book for $4.00. It may have taken me 2 minutes doing this task. The book will be delivered to my mailbox soon.
Another reason I love the internet is that through this blog I can contribute. Instead of being reactive, I can be proactive. Instead of taking I can give.
