Create Valuable Surprise!

We should consider and live up to the followings :
Our business and actions should be 'valuable' to someone or the industry.
The business and actions should surprise people and the market.

As every member continusly agonize for 'value' and 'surprise' in the work we do, we will be able to form a consensus and earn the wisdom to distinguish the works that have such values.

Eventually, we want Mobidays to give 'valuable surprise' to the world
