I believe you can only make an impact if you are happy with who you are and what you believe in. This means you must accept the challenge to get to know yourself by truly being open to yourself and the people around you. Because only then are you able to learn and develop yourself further. By remaining true to yourself and exploring new aspects of yourself at the same time, you achieve genuine personal development and become happy (or happier). Then the world is your oyster in terms of achieving what you want to achieve!
