Dai Li's mind was messed up for a while, then he finally came to himself. Dai Li knew exactly how competent he was, or wasn't. He had no experience in running a business, and he couldn't even take good care of a small supermarket, let alone a huge Group Company worth hundreds of billions of RMB.
As for Dingtian Xiao's "Learn it, if you don't know" mentality, it was encouraging to some degree, but it also brought more pressure than inspiration. Dai Li was no longer an ignorant boy, who concentrated only on study, nor was he an enthusiastic newbie, who had just started his job. He had already become a successful coach. Now, he was told to enter into a completely unknown field, and start from the very beginning, so understandably, he was confused and anxious.
