Effective leaders need to embrace internal changes, such as overcoming insecurities, learning to trust, delegating, and surrounding themselves with great people. They should be open to self-reflection, identifying areas that need change or improvement and be willing to take risks. Leaders need to ask themselves if there is something about them that needs to change, something within them that needs improvement, and something they need to do but haven't done. These questions require deep introspection and self-awareness, leading to personal growth and effective leadership.
