In a year from now, somebody will look back on today as the day you changed their life for the better. Your encouragement in all the negativity and doubt was the thing that 'tipped' them, that finally got them to believe yes it was a possibility. Whether it's a friend or a sister or a colleague or the person you end up chatting to at Grand Central. Whether you suggest they do indeed have a mind which would be perfect for law or you know a great book on business start-ups or even you stand over them while they ring the college.
Be an encourager.
