You say you don't believe it will ever happen. I know things can feel tough and discouraging sometimes but I learned that if I take action each day I feel a lot better and it gives me hope that things will get better. Each day you make choices and those choices determine what kind of country you want to live in. If you want to live in a country that never recovers from this, that oppresses people, violates human rights and causes untold global suffering you can choose to do nothing or leave comments on social media saying that things won't change or there's nothing that we can do.
Or you can choose to make a difference. How you make a difference will depend on the person. But here's what I can suggest: try to make your daily actions support moving the country into the right direction by having conversations with people, education others how to make a difference and boycott Trump-aligned companies and put pressure on and encourage organizations, institutions, companies and people to stand up to Trump.
Ceasing using Twitter can make a difference. Telling someone who says he/she might buy a Tesla not to do it makes a difference.
Asking a restaurant showing Fox News on their TV to change the channel can help.
Joining a protest can help.
Volunteering to knock on doors for your local Democrats can make a huge difference!
Even choosing to exercise more and sleep well can help because it will help you fight what's going on better.
Whatever you do no matter how small it adds up. Courage is contagious.
Also super important you vote in every election and primary and make sure you're registered to vote. Urge likeminded friends and family to do likewise. Offer them a ride if transportation is an issue.
Now I ask you: Which one will it be for you? Will you choose to make a difference or will you not?
