Being aware of enterprise politics and learning how to play them will give you the opportunity to really impact the business.
Never be the guy who says:
1. "nobody does this in the enterprise"
2. "we are doing all of this wrong"
3. "we need to start from the beginning"
4. "my manager is wrong"
Whispers and grabbing coffees with people are much better weapons than being the one that always brings the harsh truth into the meetings.
Beware: pointing fingers to a colleague or your manager to upper management is telling them that they are not making their job good enough, they are not noticing things, and since they tend not to fail and to notice everything, the failure must be you.
