To ignore the comment directed to you
Well it depends on the age of the citizen. Folks over the age of 18 can influence the government by simply voting. But, everyone can influence the government. For example, a group or band of High School students could have a protest against how Trump treats women. You could also go to the official website for your senate, representative and even your president. That can simply influence the government.
