Reaching a goal requires extra time and effort on monday or tuesday, but the feeling of satisfaction is enormous, not to mention the feeling of relief. A pleased superior might even add a bonus to the picture. Don't fade into the woodwork in meetings or one-on-ones around wednesday. Your opinion is very valid, but it won't get heard unless you voice it with force. Let your response to a challenge after thursday be to redouble your efforts and optimize your attitude. Showing you're a team player now is paramount.
