I like the idea that luck can be partially pre-engineered. The point that being more 'present' and observant of your environment so your chances of noticing and acting on serendipitous moments makes sense to me - many of the people I talk to who have made a life-changing (or even not so life-changing) career choice have done so after meeting a new contact or reading a chance article.
A meeting appeared in my diary this week that mystified me - it indicated that someone whose name I didn't recognise was going to turn up in my office to discuss something simply but obliquely headed "Reward". A few stalker-like clicks on the intranet revealed the person in question to be a member of our parent firm's HR department but that was all I could find out.
