Unplanned chance random events sometimes can have profound implications in our lives. Many a times, if we look back at our own lives, we will find that it is these chance events that leave a indelible mark on our lives. These chance events can guide us, warn us and put us back on our life's path.
History is abound with examples... Narayana Murthy might have never started Infosys, had he not had a chance encounter with a computer scientist on a breakfast table... Apple Computers might have never thought of GUIs, fonts and fancy stuff had Steve Jobs not learnt Calligraphy (totally unplanned though) during his college days. Today our finance prof was telling that he decided to take up finance seriously, only when his marketing prof asked him a question for which he did not know the answer.
To quote Steve Jobs.. "Its not always easy to connect these dots (random events) looking forward, but these dots will certainly form a brilliant design when we look back someday"
