And you may not mean anything by the complaining, but it does have a tendency to send out a negative message about your commitment to the organization and call into question whether or not you will be here in a few months. Don't share the credit. When something goes right, put your name on the top of the list of those who made it happen. Don't acknowledge others' contributions. If something doesn't work out well, point the finger at someone else.
Victory has a thousand fathers.
Failure is an orphan.
