When I was younger I worked with a colleague who was extremely good at what he did. Despite receiving lots of praise for the high standard of work he would consistently produce, it seemed he never quite realised just how talented he was. A position in the company became available which would have been a promotion for my colleague and it was widely expected that he would get the job. In fact, I overheard people talking about future plans within the company as if this person was already in the new role.
