You are a product of how you react to changes that happens around you. It is true that you may not be able to prevent certain trends from happening, but you have the option of either letting the trends define you or to have control over them. Like they say, change is constant, it's just your reaction to it that is a variable.
You have to realize that as long as you live one thing that is inevitable and that is change. Change is one of the things that affirms human existence, but the ability to respond to change is one of the things that makes us who we are.
Let's look at some life situations that can happen at any time and is beyond our control. For instance, you can't choose when the rain will fall, but at least you can just choose to go out with an umbrella. You also can't choose the direction of the storm, but you can just precisely position the sails to the direction you wish to sail.
In the same manner, you can only initiate the specific change you want by responding to an existing change. The changes you see around you are part of the actions people take. However, to experience the kind of change you want, you need to take actions that lead to change. For example, if a negative trend occurs, what you need to do is take positive action to correct the trend in your favor.
It should be noted that nothing happens without the actions of everyone. Change can be permanent, it always begins with human action. Change is one of the hardest things to deal with, simply because of the fear of the unknown that comes with it. If you can see beyond your fears, you will know how to deal with change.
A person needs a great deal of maturity to understand when to make changes that they cannot change and when to start making changes on their own. Those who approach life by chance and those who live by chance often fall victim to the changes of others.
Sometimes one action is enough to create an "exponential effect," so before you act, think about the change that action can bring. If you are not satisfied with the change, taking another action is the only option.
