I am not saying if you are a pilot and land the plane nose-down that there will not be more drastic consequences! (For my pilot friends who regularly read the blog). However, in the normal course of a non life-threatening day, take accountability in areas and ask for help when you need it. That is why teamwork exists: to assist, to delegate, to offer help to a colleague.
Conversely, when up for a promotion, identify areas where you succeeded. Highlight to your boss the big wins within the organization, and discuss the bottom line results (financial profitability, savings, new customers, long term customer retention, etc.) These are great areas to showcase when you are in an interview as well. Be aware of and proud of what you contribute to the organization.
