It’s often said that high self-confidence is key to success. In fact, low self-confidence is more likely to make you successful. Sure, extremely low confidence is not helpful, but just-low-enough confidence can help you readjust your goals so they are more realistic and attainable and have a better chance of succeeding. There are three main reasons for this:
★Lower self-confidence makes you pay attention to negative feedback and be self-critical: Most people get trapped in their optimistic biases, so they tend to ignore negative feedback. Although this may give them confidence, achievement is 10% performance and 90% preparation. Thus, the more aware you are of your soft spots, the better prepared you will be.
★Lower self-confidence can motivate you to work harder and prepare more: In fact, low confidence is only negative when you are not serious about your goals. If you really want what you say you want, your low confidence will only make you work harder to achieve it — because it will indicate a gap between your desired goal and your current state.
★Lower self-confidence reduces the chances of looking arrogant(自大的): Indeed, people with low self-confidence are more likely to admit their mistakes - instead of blaming others. This is the most important benefit of low self-confidence because it points to the fact that low self-confidence can bring success, not just to individuals but also to organizations and society.
In brief, if you are serious about your goals, low self-confidence can be your biggest help to accomplish them.
