But it was the other things I witnessed in India that really blew my mind. In the back streets of Calcutta I saw sights that just should not happen: legless, blind, ragged bodies, lying in filth-strewn gutters, holding out their blistered arms to beg for a few rupees. I felt overwhelmed, inadequate and powerless - all at once. I sought out the mission run by Mother Teresa and saw there how simple things - cleanliness, calm, care and love - made a difference to those in need. These are not costly things to give, and the lesson I learnt was simple: that we all have it within our power to offer something to change a life, even if our pockets are empty. We've come to think of charity as being about big telethons or rock stars setting up foundations, but at its heart, charity is about small acts of kindness. No matter the circumstances in which you were brought up, no matter what your job or how much you earn, we all have the capacity to give something - whether it's time, love or a listening ear to someone in need. And the thing to remember is this: don't wait until you have more time, money or energy. Mother Teresa said: It is a great lesson, and the more we try to do this with whatever little we have, the more real success will gravitate toward us. People will love you back, your own sense of purpose and achievement will grow, and your life will have influence beyond the material. That is a great way to be known and to live your life. For the record: I am definitely still a work in progress on this one, but we all benefit from trying to aspire to this more. So look around you for those in need - you won't have to look far - and your own life will grow in meaning. Success is not success unless you live this one.
