I will begin with the importance of learning from experience. It is less important, I believe, where you start. It is more important how and what you learn. If the quality of the learning is high, the development gradient is steep, and, given time, you can find yourself in a previously unattainable place. I believe the Infosys story is living proof of this. Learning from experience, however, can be complicated. It can be much more difficult to learn from success than from failure. If we fail, we think carefully about the precise cause. Success can indiscriminately reinforce all our prior actions.
