1. I think that the biggest challenge is mindset. We have to bring positivity, optimism, a belief in ourselves.
2. Failure is acceptable. All of us don't succeed on our first attempt. I can tell you, I myself have failed. For every 10 things I have done, I have failed six or seven times. I have succeeded hugely three times because I have been very lucky. If we bring overall positivity and optimism in our approach, it will take us a long way in terms of meeting the potential of what we can do to realise our true potential.
3. The most important lessons I've learnt from my father during this phenomenal journey, the first lesson is courage. Nobody has ever achieved anything big in business or in any walk of life without courage. Of course, whenever you do anything big, you do feel a little scared. But you got to conquer fear to discover the hidden hero within you. Our DNA is that we are very focused and we always believe in the principles of saying if you focus on the goal, you will overcome all obstacles. If you focus on the obstacles, you will never reach your goal.
