Approaches:

1.Millionaire – think big without constraining yourself with resource limitations. Not all of them will be doable but some can be. – Uber example

Constraint on effort.

2.Begger – clever ways of making money and saving money. AirBnB, eBay, Etsy example. Renting instead of purchasing.

Begger is constraint on cost.

3. Monk – do the minimum required. Focus on activities the people do the most, and create features that means the most.

Instead full text only sentence – Twitter.

Only sharing photos – Instagram.

Constraint of features.

P. S.

Well I think that I am a begger-monk.

Not enough resources makes us develop the most needed feature and deploy the most important business value items.
