RE:Become an ExpertThis is such a great post, and a very valuable message. Most people try to diversify across many sectors with hopes of mitigating risk. It's actually more risky to be invested in things you don't fully understand, and by spreading yourself so thin it's almost impossible that you'll fully understand all those sectors. Become an expert, become an expert. Specialized knowledge trumps all.
The jack of all trades is the master of none.
