Being well-positioned politically means people value you. But don't make the mistake of thinking that ingratiating yourself to people will help -- it won't.
While a "you scratch my back..." attitude may not be a good idea either, remembering reciprocity is a two-way street is -- especially when it comes to office politics.
With reciprocity in mind, remember, the giver has power over the recipient. That is a good position to be in.
