看了杨杰的感想，觉得很有意思，曾在Bruce Eckel的日志里读到他转抄的Robert K. Cooper的书<< The Other 90%: How to Unlock Your Vast Untapped Potential for Leadership and Life >> 里的两段内容，现转抄如下：
Now, you may think that your passion for Icelandic poetry of the baroque period, or butterfly collecting, or golf – or social justice – might consign you to a permanent separation between what you love and what you do for a living, but it isn’t necessarily so. Vladimir Nabokov, one of the greatest novelists of this centurey, was far more passionate about butterfly collecting than writing. His first college teaching job, in fact, was in lepidoptery. REsearch on more than 400,000 Americans over the past 40 years indicates that pursuing your passions – even in small doses, here and there each day – helps you make the most of your current capabilities and encourages you to develop new ones.
