Yeah... it is good. Regular investing... easy money.
You'll be lucky to reach 23% though. The index average of the FTSE is about 11%... I think the DOW is roughly the same.
Even Buffet himself thinks that the 20th century and now is the 'golden age' for capitalism and there might be tough times ahead. Still, an 11 or 12% rise each and every year will still make you rich.
