In near future the way the people are going to thrive they are going to be needing how to survive by being assertive. If not we would be under pandemic like situation where each one would attempt to live for their own self. And this would also make the competition to survive a bit more fierce as well.
In near future we would be around the people who would be making it harder for us to thrive and survive. Why? Because there would be rise in poverty and the competition to survive would be higher. And this would lead to the ecosystem where people would try to steal each others resources.
This also shows that there would be some of the sins in mind of people. Like resentment, grudge and other things which would make it harder to survive when most of the people are trying to grab your survive and then that would hurt the future that people have. Because more people compete and more people would hurt each other there.
During this approach you would also notice that people would exert the dominance using the body language. And this would make the assertive nature of the men even more visible and also this would affect the future that we are trying to live with. In such case you can see that surviving in near future without being assertive would be thought.
First approach you have to do is understand where to make your voice heard. And also you have to use the I and we as conversation. Some of us you would notice that you can add your voice and the opinion being pushed and being heard on that part.
Second emotions have to be in check. Make sure to not make some other people more desperate. And also the emotions of the desperations would hurt the people in the long haul too. Like you would lose out on the conversation if you make other people uncomfortable.
In short being assertive is a lifelong process and also that would hurt the survival of the people in near future if they choose to be not assertive. In short being assertive is a need in current times.
