Of course, the difference is quite far between the older generation and the current generation, but I don't care about it even though young people nowadays tend to move from job to job, I always emphasize to my children that they can focus on a field that has long-term opportunities, it is better to be an expert in one field than to have a lot of experience in many fields that makes them a generalist, I think if you have a specialist in certain skills it will be more expensive than just having ordinary abilities like most people, in this case you need to teach the supply and demand of long-term labor to have high value.
