You must know that change is the only constant thing in this world. Every day, the world is changing at a considerable speed. It’s a different matter that the change is good or bad; but it is changing. So, if you think that you need to change something in your world, you should start it by yourself. And only after that, you will see everything will fall into place.
We tend to think that some other people will bring change. We forget the fact that if we have to change, we should start it by ourselves. We sometimes think that we are perfect individually. But, there are no such people in this world, which you can consider complete. To be precise, there is no existence of perfection.
So, it will be best for you if you can introspect a bit and find out the issues inside you. If you can comprehend your problems, it will be easier for you to change. And if you can change yourself, it will be easier for you to change the world.
So, at first, bring the change in yourself, after that you can think of changing other people. And to bring the change, you have to change your thoughts at first. Or else, no one can help you to change the world. Once you change your thoughts, you can consider yourself prepared to bring the change.
