I disagree that they're rebelling in the conventional sense, since they aren't rebelling against anyone, they're usually evaluating rules, and if the rules don't fit them, they'll break them with no guilt whatsoever.

At least that's what I've seen in the small group of entrepreneurially minded kids I've met and got to know(4-5 people, a ballpark estimate would be 1% or less of people I know).

I also don't entirely agree on the financial backing part. 3 of them have financial backing, but all 3 earn their money themselves. The other 2 have no, or almost no financial backing. One of those is an outlier, since he had backing from his father, but it's uncertain whether he'll have it in the future.

One curious observation that I've made is that they all have a slant towards doing marketing. 2 of them went to college in order to study it, another 2 are doing freelance work at it, and the last one is intrested in it.

Also, 4 of them program, the 5th one not being intrested in it.

On the point of self esteem, they all seem to have very high self esteem.

I have to say that 5 people is a small set, and whether they'll be sucessfull as entrepreneurs is only something time will tell, so I've only included characteristics that occur in most of them very strongly. Still, it's a set of teenagers/young adults that allready know they want to be entrepreneurs, so it fits quite well.
