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
It's just with a fixed mindset, assuming that they are enjoying themselves, but they won't grow. They are satisfied with whatever state they are in in life. It seems like, being an employee, there are others who are satisfied with their monthly salary, or 15–30 date of the month salary.
There is sure that they have something to pay at the end of every month or 15–30 date. But they also know that they won't grow because they don't leave their comfort zone. But if you have a growth mindset and the system you are using is right, for sure, in the end, you will be successful.
