Two of my friends work for companies that encourage curiosity and life-long learning in their employees. One company offers a monthly stipend for an employee to take a class in anything, unrelated to the employee's job role: it can be a class in dance, art, music, etc. Another company offers a birthday "present" of funding for the employee to do something (anything!) and requests that the employee report back to the team about what he/she did. I love that an individual's personal interests are encouraged, and that employees are encouraged to develop and share their lives beyond their work. Students, too, should be asked about what they're curious about, and given chances to pursue those interests.
