Why is it not as good as a newcomer to work for three years?

There is a saying that goes like this:

Experienced people are not necessarily experienced; An experienced person must have experience.

This means that it doesn't matter whether you have experience or not. The key is to sum up and think in time during the experience process, and then form your own experience. Guide work through experience and improve self-ability.

I hope it helps you!

Have a nice day!
