Are all entrepreneurs belong to one category?

They do tend to fall into categories that we can attribute some specific characteristics. These categories are

1-Serial entrepreneurs

Is someone who focuses on starting multiple businesses one after another.

Their focus is to find one new firm, typically selling that firm first and then starting their subsequent firm. An example of a serial entrepreneur is Steve Jobs.

2-Parallel entrepreneurs

Is someone who manages to run more than one successful business at the same time.

 Steve Jobs incidentally was also a parallel entrepreneur when he was running both Pixar and Apple at the same time.

3-Non-traditional entrepreneurs.

This include people who create jobs for themselves in a variety of idiosyncratic ways by establishing businesses on their own.

This often results because as the global economy has evolved, lots of multinational corporations have significantly redistributed the production and services to take advantage of cheaper labor.

4- Micro-entrepreneurs

Workers who need to run more than one job at the same time to pay bills, they're doing this often to offset difficult economic times.

What are the entrepreneur’s common traits?

There are a few things that we do know from research about entrepreneurship with some evidence that:

1-Entrepreneurs are more likely to exhibit overconfidence.

2-Entrepreneurs are more likely to demonstrate some optimism,

 So in studies that have looked at social capital, incognition, and entrepreneur opportunities, we see that some levels of optimism that are over and beyond the general population,

as well as overconfidence.

3-Risk propensity. There is some research that suggests that entrepreneurs are more likely to tolerate higher levels of risk, but other findings show that there's no difference in terms of risk propensity at all. 

4-Entrepreneurial passion very often, 

But on the whole, most research has produced mixed findings on particular traits and attributes that might define an entrepreneur. Findings related to other

traits are really mixed.
