There are two ways to establish competitive advantage – do things better than others, or do things differently. What we can or cannot do, what we consider possible or impossible, is rarely a measure of our true capacity. It is more likely a measure of our beliefs about who we are.Therefore, my dear students keep striving, to achieve all within your capacity. Keep moving till you touch the heights meant for you. Nothing needs to bother you, nothing needs to worry you. “Master yourself” – the excellent piece of knowledge – one can achieve.
