What was accurate in the past does not mean it is accurate now
Past experience is useful, but it does not mean it is still effective
If you continue to live in the past, it will be difficult to make progress or develop, so you must live dialectically
I was working on telecommunications engineering in Africa in 2008. Back then, it was relatively simple to do engineering. By 2010, the model changed. If you still use project management experience from 2008, things might go wrong. After returning to China, I was in sales in 2015, in sales again in 2017, and in 2021, indeed, there are new models every year. Referring to previous experience is somewhat useful, but not absolutely useful; that’s roughly the meaning
You cannot completely rely on past experience, especially when making significant investments.
