Despite this path being unclear you have to hold tight to the voice in your heart. The most important thing is not having an idea but being able to execute effectively.
With various opinions you need conviction to see your dream through to reality. During my Masters program I learned a great lesson and that was to believe in and trust my instincts. I compromised an idea that became diluted and lost traction.
If you try to please everyone you fall into the middle of the road category. You must stand out to be strong!
Otherwise what is the point.
