I've been investing (along with Nords) in mostly Hawaii startup (Angel investing) since 2006. So far the track record has been pretty poor (some good tax credits early on), a couple of outright bankruptcies, and bunch while still surviving still face tough challenges. This year one of the companies hit a home run. They paid out a cash dividend (actually in Jan so it's not part of my calculations) that greatly exceeded all of my investments in the company. The stock price has increase 5 fold. Fortunately, it was the company I was most optimistic about and invested every chance I got and so single handily turned my Angel investing from an expensive hobby to a profitable one.
This led to an increase in my liquid net worth by 17.9% despite spending like a 1/2 drunk sailor most of the year.
