Yes indeed so please darkworkers, realize QUICKLY that money, big cars, big houses and ownership of big industries won't make you really happy. it will save the atmosphere from getting more CO2 if you realize it quiclky.
Power will not make you happy either, try to realize that, it will save some people's freedom.
Low level darkworking is bad for the planet and others, especially if you have lots of power (through money for instance) to spread it.
However, low level lightworking can also be really bad. Some example of low level lightworking might come under what is called "idealism" in theory of international relations. Idealists act not for their personnal well being but in the name of a certain ideal. Some example of idealism in international relations :
-Kamikaze bombing and terrorism. Yes, terrorists don't act in the name of their well being but in order to serve what they perceive to be God and its creation.
-The holy war or the war against "the axis of evil"
These are just examples of LOW LEVEL idealism though.
So if you choose the lightworking path, think well before forcing your light into people's life. Rather SHOW the light, and let the people decide for themselves, even if when you show the light, people laugh at you first. (I guess sometime anyway it is necessary to "force" the light but just be careful when you do it ok).
Whatever path you choose, be sure to raise your consciousness.
Anyway, I think that if we realize that there is only One Universal Counsciouness, and we identify with it, we strive to serve this counsciousness (which includes your "avatar") and that is lightworking to me.
I really can't think of being anything else than a "lightworker".
