When it comes to building up a career, a lot is said about network and leadership, but one important thing is neglected, and this one thing might be the most powerful weapon in your corporate armory: self-knowledge.

Often overlooked, this skill can be helpful in a number of situations. No matter what kind of job you do, challenges are always a part of it, and to perform well, the first thing you must do is feel good about yourself.

Whenever you face an obstacle or have to leave your comfort zone, it’s easier to handle it when you know yourself well. Self-knowledge has a lot to do with being able to control your emotions. In crisis moments or dealing with delicate situations, knowing your goals is certainly a great way to overcome it.

Self-knowledge can be a powerful source of motivation as well. It’s common knowledge that people can’t be good at everything, but we tend to forget this on a day-to-day basis, and get upset. When you are aware of what your strengths and weaknesses are, you can focus on your strengths, establish achievable goals for yourself and avoid frustration.

Having this knowledge is also a great way to choose the right work for you. Being an entrepreneur or a manager, for example, isn’t for everyone. You can be a valuable asset, and once you discover how, your path is likely to be much smoother.

But even in an area that you shine, negative feedback can happen. Self-knowledge will also help you to process criticism in a positive way. Once you’re secure of yourself, you’ll start developing emotional intelligence and react to critics in an impersonal way.

It’s crucial to know what your values, beliefs and goals are. Knowing who you are and what you’re made of is going to push you further in your career.
