contentment vs complacency

Why do we stay where we are? Why stay in a place where things obviously are not changing the way you think they should? So often we look to Paul's writings about being content in all things as reasoning for staying put. There is value in that under the right circumstances. But at what point does it become an excuse for complacency, for not stepping out and doing the right, albeit the harder, thing? That is the question I am left with tonight. I know the things I am passionate about. I know what I was called to a year ago. And right now they don't go well together. SO am I staying because I should or because I'm afraid to go? I don't know the answer to that question yet.
