SELLING yourself short is a figure of speech which means you are not giving enough credit to your gifts or abilities in some way. It’s not recognising that you have great value and importance.
You don’t believe you or your gifts or abilities are worthy what they really are.
To sell yourself short mean not living up to your true potential or be a part of something higher — personal standard and bar of self-worth, self-expectations, aspirations, dreams, goals, moral character and code of conduct, ethics and core beliefs system of values. It means a personal letdown.
CONCLUSION: So, don’t sell yourself short, whether as an individual or a company.
