Instead of being anxious or fearful, we should actually ask: what can we do to make our world, and our life, a little better?
Is it to be a little nicer to others, and yourself? Is it to do the best you can at what you do? Is it to clean up your act, to pursue your dream?
I'd like to think that changing the world, starts with yourself. I'd like to believe that when you try to be the best version of yourself, trying to do the things you really want to do, things work out. And the world gets a little better because YOU get a little better.
This may be a very selfish, millennial worldview, but I think that successful, worthy causes begin because people want to see something happen--and if others follow or support them, so be it. Successful causes begin because someone is trying to do something good, for their own mission in life (i.e. Gandhi, Martin Luther King, Jr.), which happen to align with the voices and wishes of the timid.
Making a positive impact means living your true self, and going to go get what you deserve. Making a positive impact means inspiring others to do the same --- with you as the example.
In some ways, we are living in a stable, peaceful time, at the best moment possible, to pursue your dreams. In other ways, we're living in a fearful time, full of trials and uncertainty. Politicians on different sides of this debate claim they have solutions to the ills of today -- such as lower taxes, free education, or even more (or less) nationalism -- but merely, they are only treatments to the society's symptoms, never getting to the real root causes. We need to get to the core truths, and question assumptions, and find alternate points of view. Most importantly, we have to encourage ourselves, and one another, to be the best we can be each day, to try the best we can.
