Stacy Blackman provides excellent advice on how to be authentic and impressive in your business school application essays. Simply writing about your passion, however, is not enough to make a great essay. Avoid going into too much detail or being too obvious about how the skills developed while climbing a mountain will make you a persistent entrepreneur. Try to let a single, well-chosen anecdote speak for itself. The same advice applies for essays addressing your weaknesses: discussing your failure is an excellent way to demonstrate self-awareness and the desire to improve yourself, which are critical for getting the most out of your MBA.
