You should never think that your single vote can't make a difference, because it can.
In 2000, the United States Democratic Party representative Al Gore lost the Electoral College vote to George W.Bush. The difference in votes was so narrow that it triggered a case in the Supreme Court and forced a recount in Florida. Bush won by 537 votes, which is around 0.01 percent of all voters in the United States. If just 550 more Democrats or Al Gore supporters voted in November 2000 then there could have been an entirely different president - just a few hundred votes could have changed history. Even the 2016 election was very close. Although, Hillary Clinton had won the national majority by 3 million votes the number of Republican and Trump voters in swing states gave Trump the victory.
Although your vote likely won't directly elect your new president/senator it can make a difference when it joins other votes in your district, this is especially important in states with winner-take-all situations. In local elections, your vote matters much more because there is usually a small voter turnout. A study by the Portland State University found that less than 15% of eligible voters turned out for local elections, meaning that these elections are determined by a smaller group and one vote, therefore, is more impactful.
Even if you aren't an eligible voter you can get involved with the election process and voice your opinions by learning about political issues and possible solutions. Do this by volunteering for a party or candidate's campaign, reading up on political issues and thinking about possible solutions, and by voicing your opinions either in public or on platforms such as social media or your local paper.
