Once you learn the techniques of true Leadership And Influence, you will be able to build the confidence it takes to take the lead
Leaders are born, not made. While it's correct that some people are born leaders, some leaders are born within the midst of adversity. Often, simply those that haven't had a leadership role will arise and take the lead when a situation they care about requires it. An easy example is parenting. When a toddler arrives, many parents discover leadership abilities they never knew existed to guide and protect their offspring.
Once you learn the techniques of true Leaders & Influences, you'll be able to build the boldness it takes to require the lead. The more and more experience you have acting as a real leader, the better it'll be for you. It's never easy to require the lead, as you may make decisions and face challenges, but it can become natural and rewarding.
