Actually, Nikhil had the right idea: self-reflection can be extremely effective for entrepreneurs looking to maximize revenue. That's not to say that external factors shouldn't be taken into consideration–of course they should, but they don't negate the importance of self-reflection. For example, entrepreneurs may use self-reflection to ask the right questions about their customers and the industry, which can help them to identify better strategies.
Furthermore, self-reflection is an incredibly powerful tool for entrepreneurs to hone their focus and remain disciplined in pursuing their goals. Asking oneself difficult questions and truly reflecting on the answers can help entrepreneurs stay motivated and push through difficult times.
Finally, building a successful business requires more than just a good strategy: it requires hard work, dedication and a positive attitude. Self-reflection can help entrepreneurs cultivate the mental fortitude needed to be successful. So, while external factors are certainly important, becoming successful requires a combination of reflection and action. Ultimately, Nikhil's original advice of looking in the mirror is still valid! After all, entrepreneurs often need to look within themselves in order to find the motivation, focus and grit needed to become successful.
