what actually motivates people to work (My Bad for the previous post)

What motivates people is the significance of their works.
What might sap one's motivation is when their works became insignificant.

One effective way to motivate people is making their past work useful and significant.
And to deal with insignificance of one's work, is to do something significant.

What might makes people tired of working

Are their past achievements.

TravelTeam, Youtube subscription partition

Making a TravelTeam ticket, a travel ten for 2 people or more.

Since Gmail has partitioned our inbox to primary, social, and promotions... it would be very nice if youtube also could partition the subscription page into channels that frequently updates, moderately updates, and rarely updates. The purpose is to prevent the rarely updates from being noised out by frequent updates of other channels.
