This is fascinating to watch: People are getting seriously rich-ish on this forum (everyone has their own definition of that, but it is what it is) and it's fun to read about how people handle it. From my dot.com days I remember these bits:

1) NEVER CONFUSE LUCK WITH SKILL
2) Some people will cash out for hookers and blow
3) Some people will not cash out for hookers and blow.

Fun to watch.(1) is critical, I can't tell you how many dot.com millionaires thought it was because of their super l33t skillz and founded companies that ate all their money and then some. Never confuse luck with skill.
