If you were unable to do that exercise, you may have something blocking your ability to feel confident that runs deeper than I can go with you as a career coach.
However if you were able to do the exercise, congratulations! You now know that you only lack confidence in specific situations. Now, because these situations are work related, if it has to do with your craft, then keep working on it. Preparation and practice will build your confidence. If business is the area where you're lacking confidence, it too is a practiced skill. Business and networking skills take practice just like your craft or tying your shoes.
Look over the topics of my past blogs to find the areas where you need practice. If you can't find the answers you're looking for, be more specific next time you contact me and I'll give you some techniques to work on.
