Being an effective leader is critical in any leadership role. Being an effective business leader is foundational to the success of your business! Without effective leaders, your business will never reach its full potential!
I have seen all kinds of business leaders over the years; destructive, bad, subpar, average, good, excellent, nurturing, multiplying, etc.. In each case, the level of success of the business was directly reflected in the quality of the leader.
The destructive, bad, and subpar leaders have businesses that perform at these same levels and most eventually fail. Average leaders have average businesses while good, great, and excellent leaders create good, great, and excellent businesses! There may be cases where a business will perform above its level of leadership but this never lasts long. The level of business success always settles to the level of leadership effectiveness!
