You cannot take your team to the next level if you haven’t identified the next level. Likewise, you can’t identify the next level for your organization or department’s vision of success if you haven’t exposed the next level for yourself.
There is always another level to everything, including your leadership. Leadership is about getting people to appreciate and invest in your mission. Working with and managing your team to accomplish your goals is all about maintenance and seeing that things happen as they should every day. Both are necessary, but only leadership will take you to the next level.
