A mistake many people make in their understanding of how confidence affects them is to believe that it is something that they either have or don’t have, and if they don’t have it, they will never be able to get it. To the contrary, confidence is a skill that develops with awareness and practice. Think of confidence as being like a sports skill. If you practice bad technique repeatedly, you will become very skilled at the bad technique and that is what will come out in competition. Additionally, that ingrained bad technique will make it more difficult to learn new good technique because it will be ingrained into your muscle memory. Conversely though, if you practice good technique, that is what you will ingrain and that is what will come out in competition. The same holds true for confidence. If you practice being negative, worried, and discouraging, then you will become skilled at the negativity and that pessimistic mindset will emerge when you are in an important business situation, such as a sales call or under deadline to finish a work project.
