It is common to feel under-confident when you first start as a foundation doctor. After all, you are not automatically omniscient just because you have gained your medical degree. Some people hide their emotions better than others. Many appear confident but, if asked, would claim they are not really underneath. Building confidence comes with time and experience. However, even top consultants will admit that they are sometimes flummoxed. The key is to know when you need help and to be able to ask for it appropriately from the right person. However, you should have some faith in your own ability. Some people under-estimate theirs.
