"1. Two obsessions are one too many
Experiments, like many speculative enterprises, are likely to require at least five times more effort than you initially guess. Being a really good anything - be it university president, violinist, securities lawyer, or a scientist - requires a virtually obsessive devotion to ones' objective. Dividing one's attention will give the edge to competitors who have the same talent but greater focus. For this reason, highly successful bankers who also claim to be accomplished cellists are often neither. Their banking reputation likely rests on the labors of talented associates working day and night, and their cello playing as likely suffers from the time lost to even the pretense of being a banker."
