What does it take to be a good revolutionary?

So, I was looking around on wikipedia and I noticed that the definition of revolutionary is: a person who demands fundamental change in power or organizational structures, constitutional change. a person who demands it NOW.

By that definition, and looking at all the out of control drug laws and military spending and what have you, I guess most of us are revolutionaries, but none of us are any good at it. why is that?

To Para-Phrase Che Guevara "When a government has gained power through some sort of popular vote, fraudulent or not, and maintains at least a appearance of constitutional legality then guerilla warfare can be promoted because not all political alternatives have been exhausted" - Replace guerilla warfare with revolution (or some variation on revolution) then you will have your answer.
