Microsoft has posted a video over on Technet that goes over some of the cool things you can do with Powershell. I think it is a great video since it starts are with some pretty simple scripts and keeps building on them. This just scratches the surface on what you can do with powershell but will hopefully motivate you to learn more about Powershell.
In the everyday grind of work sometimes a funny video can help get you out of your funk. I was introduced to the Very First IT Technician and found it pretty humorous. The video looks at how the transition was made from the scroll to the book.
Randy Paush passed away on July 25, 2008 after a long battle with cancer. He has helped inspire millions of of people including myself. He has become famous for his Last Lecture which was recorded shortly after he was diagnosed with cancer. If you have not watched it I highly recommend it. I guarantee that you will find at least one thing that will help you in everyday life. I also highly recommend watching his video on time management. We all need help with on that subject.
