However, very few will want to accept that certain elements of their character will prevent them from excelling and getting the remuneration they deserve for their efforts.
Still, it appears a handful of Britons could benefit from building their confidence levels in order to approach their bosses about a pay rise.
Research from Stagecoach Theatre Arts School found 34 per cent of people questioned were too shy to ask their boss for a pay increase.
The study also found 29 per cent were too timid to go for a promotion, which will no doubt impact on their ability to excel in their jobs.
Director of education at the Stagecoach Theatre Arts School Veronica Bennetts believes that confidence building is important from a young age.
She said: "If you are shy, it can mean you struggle to sell yourself in job interviews or find it difficult to deal with customers or clients when you are at work."
Indeed, the study showed 29 per cent of respondents struggled in job interviews and found it difficult not to clam up when asked important questions.
A further 41 per cent of people got nervous when delivering presentations or heading up meetings, while 40 per cent were too shy to open their mouths at meetings altogether.
This level of shyness could, however, put a stop to the amount of income a person secures if they are too inhibited to request a pay rise or aim for a work promotion.
While this not only has obvious hindrances for people in their current roles, it also prevents them from earning enough to boost their savings for later life and retirement.
As such, those struggling with confidence issues might consider ways to improve their public speaking skills so they are less fazed by their colleagues and seniors at work.
