Fear of risk taking: Taking risk could be harmful if not calculated but not taking risk is even worst cause their are many opportunities involved in taking risks, a good percentage of successful people today are risk takers, so I believe the journey to success still requires taking risks.
I believe there's lots more, but these are the ones I could think of however you could add more if you know any cause I believe these informations could serve as a motivations to some people who would come across this thread.
The point is not to let income be greater than expenses because if that happens then anyone will find it difficult to gain wealth.
The process of gaining wealth must be prepared for many things and risks must also be calculated according to one's ability to live.
Most people take risks based on careful calculations and they know the impact of taking the risk.
If you take risks without calculating then that is called gambling because people do not understand what is at stake in the risk.
information must also be studied because the current condition is a lot of misleading information, learn to do something right so that the decision when you want to start has a correct knowledge.
If a person makes a decision without involving knowledge, he will not get any results.
