Additional Information: This quote is from engineer RA Mashelkar's 2009 TED Talk in which he shares the stories of how innovative design made expensive products, such as cars and prosthetics, available to the general public in India. The quote means that if you believe that something can be done, even though someone else might think it's impossible, you will be able to come up with a creative solution to make it happen.
