⑴ Several important things when starting a business: first, work hard; second, attract outstanding talents; third, focus on making products and services better; fourth, do not just follow the general trend. Walk.

⑵ If you believe that there will be more opportunities in the future, you have no reason to feel sad about the lost opportunities. Only when you lose more than you might gain do you have cause for regret.

⑶ Treat knowledge as a semantic tree - make sure you understand the basic principles, just like the trunk and large branches, and then look for the leaves/details, don't let them have nowhere to hang on. This transforms knowledge into deeper, abstract principles and promotes learning transfer.
