The needs and WTP. Research.

Everything that is being sold is meeting someone’s need. - table, chair, car, keyboard, books, notebook, pan, mobile, headphone, bottle. Bag, electricity, co-work space, place, play board, clothes, wallet. Post, iPad, safari, subtle, icons, delivery system. All these things are meeting need and getting the creator paid.

For IPad my wilingness to pay is 30-35K, for svbtle it is no money, for the book up to 800rs, for headphone 2000rs, cowork space 6000k, pan 80rs. They are based on my previous experience and capacity to afford.

How to do this research -

• what are the product I am using and what need and want they met.
• what are the product brother, Lin, Akhil, mom using. Check the amazon history.
• what are the top selling product and what exactly they are selling.

The first information you need to skim out is the need and wants of yourself, and people who are willing to share their information.
