Dan Pink’s book “Drive” emphasizes the importance of “intrinsic motivation” for a modern day knowledge worker.

He makes a mention of the iconic company named Atlassian(invented Jira ,Confluence etc. agile software lifecycle tools).

To encourage creativity as a drive towards intrinsic motivation one day every quarter is celebrated as “FedEx Day” wherein anyone can develop anything of his or her choice provided something is shown as a deliverable.

Amazing thought process!!
