The term 'Lack of Boldness' can be summed up in one word: TIMIDITY. TIMIDITY is defined as a lack of courage or confidence, often resulting in a reluctance to take risks or act. It is a common trait among people who are shy or introverted, and it can also be seen in those who are afraid of failure or rejection. In some cases, TIMIDITY can lead to a fear of taking action or speaking up, which can have a negative impact on personal and professional success.
