I have known a few entrepreneurs and invariably they showed they were such by their behaviour, attitude and approach. They did not need someone to tell them or need to stop and ask &quot;Am I an entrepreneur?&quot;, they just got on with <i>being</i> one. The same applies to a cartoonist, or comedian etc. Often in fact these people do it despite advice from competent people and even their loved ones. Advice like: &quot;What, why give up your place at an ivy league university to go open a car wash, that is just crazy!&quot;.
