I got lots of rules, but my most important one is that 'there is no such thing as a missed opportunity.'  Following this, I will never rush in to buy the next big thing without first performing due dilegance.  You might say it isnt true, but then I would say that there is a great opportunity every day of the week.  So if I missed yesterday's then I only have to find today's.  And you only have to find a small number of them to truely be successful.
