TED talks are a great way to pass the time and learn new things. Topics range from the truly bizarre, such as 'How to Use a Paper Towel' to more serious (and professionally relevant) discussions on ethics, politics, crime and war.
This series of 6 TED talks on 'The Benefits of Failure' offers great insight on how to turn a negative experience into an opportunity to grow and succeed.
While you are in a TED frame of mind, why not also check out another great series '14 War Stories', which includes first-hand accounts of various conflicts and discussions on military strategy.
