As an entrepreneur, try to be a subversive, not a rebel.
Here's how I differentiate between the two:
1) A rebel breaks the rules because he or she hates being told what to do. A rebel's defiance is open, and being identified as a rebel is a feature, not a bug.
2) A subversive breaks the rules because he or she is trying to accomplish a goal, and breaking the rules is the best way to accomplish that goal. A subversive's defiance may be secret or open, depending on which is most likely to help accomplish the desired goal.
Subversion is rebellion with subtlety and purpose.
Napster was about rebellion--it was clearly illegal and the company didn't bother concealing it.
Pandora was about subversion--finding a loophole around streaming royalty rules.
Rebellion can change the world, but it often flames out. Subversion is subtler, but has a higher chance of success.
