Since this is a "Personal" Development website I imagine everyone here are darkworkers or you'd be at a save the whales website right?
Just being a lightworker gives way to being a darkworker. Why give? Because that is what you LIKE to do, it makes YOU feel good or is based out of fear. Sounds like personal motivation... a trait of a darkworker... If you aren't in this game for yourself you'd be dead already.
The technical semantics of Steve's polarization don't fit BUT I do see what he is getting at... Just stick with what you feel, your not wrong. If what you feel isn't doing what you want then try leaning more toward your stronger side of the scale and get those emotions fired up.
