Work on conflict resolution skills
Improve your conflict resolution skills so that you can always find a compromise in challenging situations. Sometimes our lack of confidence arises from thinking such as "if something horrible happens, I won't know how to act or respond."
As a result, we opt to remain in our comfort zone. It's important to master problem-solving since you'll need to know how to act and respond before your feared event occurs. Learning what to do or how to behave in awkward social situations can offer your personality a huge confidence boost.
