No act of kindness, no matter how small, is ever wasted. - Aesop
Google is credited for creating 20% time. Google employees spend 20% of their time, working on projects that are not included in their job description. As a result of 20% time we now have Gmail, AdSense and Google News. Before Google had 20% time, another company in the 1950's called 3M had '15% project' time, as a result in this time Post-its and masking tape were created.
