When people seek help from others, they generally aren't as well-prepared as they could be. Only when you "know thyself," your own goals, strengths and weaknesses, are you able to figure out whom to turn to for support...and...know how to ask for and apply the advice you receive effectively.
Are you comfortable reaching out for help, sharing your experiences and soliciting feedback?
Admitting a flaw or weakness shows people you’re human. This is essential for building trust and rapport. When you share that you’re not a morning person, can be somewhat disorganized or are nervous when speaking in front of large audiences, you’re being transparent and authentic.
This authenticity displays your willingness to trust people enough to be vulnerable and real—and they generally want to return that trust. Exposing a weakness helps get people onboard. If you solely communicate your strengths, others will have no desire to help you out.
That said, you should select which flaw to reveal wisely. Never expose a weakness that can be seen as a fatal flaw critical to a central aspect of your professional role. Confessing to a lack of attention to details is inappropriate in a financial leadership role. It would be better to admit to tangential flaws that don’t affect your performance.
Another well-known strategy is to pick a weakness that can be considered a strength, such as being a workaholic.
An overextention of a strength can be a weakness in certain situations. It has been said that every problem is a 'nail' for those who are good with a hammer.
Again, the most important quality here is authenticity. If you expose a vulnerability that isn’t real, people will be quick to spot the incongruence.
