Stop being afraid of owning up to mistakes. Simple mistakes. Typos. Everyone makes them. Own up to it. That way, you can be held accountable so that, next time around, the same issue won’t arise.
If a typo surfaces in your e-mail and someone calls you out on it, it’s as simple as saying “Wow. I must have been writing too quickly. My apologies.”
If you can’t take ownership, you’re not an asset. Recognize your flaws and adjust them accordingly. It’s the only way you will be able to lessen the impact they have on your career.
Make professional development a priority.
