Growth mindset is hard to achieve. Humans tend to look for comfort and stick with it until something happens. No one really wants to get out of their comfort zones until they are forced by an event or a difficult situation. Rarely have I ever encountered a person who wants to change something and actually do something about it, though it is still possible with the right approach and the right support.
Franky1 mentioned career paths and it is one of the prime examples of this. We tend to specialize in something until it occurs to us that we no longer want it or there are other high-paying jobs that we 'might' get a liking to. Economic conditions force people to change jobs and grow, but if the economy is good and our salaries still fulfill our expenses, I guess no one will have to hop jobs and companies every now and then.
The difference between a fixed mindset and a growth mindset is that a fixed mindset means that they always enjoy the current situation without acting on new things and don't care about any innovations so they are always in a safe condition even if there is a downturn, often they consider themselves unable to do things beyond his abilities. whereas those with a growth mindset always look for new challenges in life as long as it brings positive things to themselves, they see that whatever failures will one day bring change to themselves, if they hear and see other people succeed they continue to find out and ask for experience and how to be successful like that person
The simple thing is that when we have a developing mindset, we are indirectly ready for the challenges we face, but on the other hand it is very good to do because in the end this can also be one of the encouragements for us to upgrade ourselves to be better than before because indeed with the progress of the times that is always better as time goes by, we must also indirectly have a developing mindset to keep up with it.
As for those who are in a fixed mindset, it is actually not a problem if they really want to do that when their resources are enough to be in the comfort zone but on the other hand we also cannot be an idealist in addressing situations that occur in development because in the end we also have to keep developing ourselves unless we want to be left further behind.
