In her recent speech,
she mentioned what Professor Zhang Weiying said to her:
The stove should be small, and the fire should be strong.
Shrink the scope a bit, focus on the things you can do well; but the fire in your heart must burn even brighter, maintaining passion and strength.
You see, it's the same meaning as what Buffett said.
Without focus, professionalism, and passion, it's hard to achieve excess returns in investment.
The secret to many things,
ultimately boils down to those common sense principles.
