When it comes to success in business and success in life, there are few qualities as important as confidence．

People naturally have different levels of confidence．Some have a higher level of confidence than others do, but even those whose confidence is lacking can learn to build their level of confidence and reach their most important goals．Increasing self confidence is one of the most common reasons people give for seeking the help of psychologists and other professionals．

One of the many places where a greater level of confidence is useful is in the workplace．We all know how difficult it can be, for instance, to ask the boss for a raise．This process can be extremely difficult for those who lack confidence in their own abilities．After all, if you are unsure about your own abilities, how will you ever convince your boss that you deserve more money for the work you do?

Even if you are not asking for that big raise, having plenty of confidence in your abilities is important to success．If you are certain of your abilities, chances are that those around you, whether they are your coworkers, your colleagues or your superiors, will see that confidence, and that will help to assure them that you are the best at what you do．

Being thought of as the person to go to, and being seen as an expert in your chosen field, is naturally very important to success on the job. If you can make yourself the person people go to for guidance and advice, you will help to protect yourself from the ever present danger of downsizing. After all, if you are a recognized expert at the office, you will be regarded as an indispensable member of the team.

Having a high level of confidence, after all, does not mean overlooking the places where you could improve．Knowing what you do well and where you need help will help you enjoy increased success and confidence．
