The first is previous experience. Previous experience in a particular industry helps entrepreneurs find opportunities. Some surveys have found that about 70% of entrepreneurial opportunities are actually copying or modifying previous ideas or ideas, rather than discovering new entrepreneurial opportunities.

The second is professional knowledge. People who have more professional knowledge in a certain field will be more alert and sensitive to opportunities in that field than others. For example, computer engineers are more alert and sensitive to the opportunities and needs of the computer industry than lawyers.

The third is social networking. It is an indisputable fact that the depth and breadth of personal social network affect the identification of opportunities. Usually, people who have established a large number of social and expert contact networks will get more opportunities more easily than those who have a small number of networks.

The fourth is creativity. To some extent, opportunity identification is actually a creative process, and it is a creative thinking process that is repeated repeatedly. Creative thinking can be seen in the formation of many products, services and businesses, and even in many interesting business legends.
