Below is a partial list of the rights you have under the Constitution (though some may depend on your age). Remember, thanks to the Tenth Amendment, you and your state also have the right to decide on any issue not directly addressed in the Constitution or its amendments.
To say what you need to say
Regardless of who's in power or what the majority opinion is, the First Amendment ensures your right to speak freely and assemble peacefully. You have the right to make yourself heard in the national conversation.
Pray to your own god, or not
The First Amendment also prevents the government from establishing a national religion or ruling on religious practice, which means you decide which god you pray to, or if you pray at all.
Through elections, the Constitution assigns authority over the government to the individual. You have the right to participate in selection of your representatives, without interference.
Regardless of your race, ethnicity, gender, or religion, the Constitution guarantees equal protection under the law to all citizens of the United States.
To your property
Be it unlawful search and seizure or forcing you to house troops, the Constitution prevents the government from using or taking your property.
To Carry a Gun
The Second Amendment protects your right to bear arms for self-defense, as well as the right of the state to maintain a militia.
To a fair trial, and fair sentencing
The Sixth Amendment states that all citizens have the right to a speedy, public trial by an impartial jury. The United States' ban on "cruel and unjust punishment" is stated in the Eighth Amendment, along with protection from excessive bail or fines.
To individual freedom and local governance
The Tenth Amendment reserves any powers not explicitly given to the Federal Government to the States and the people. Not everything is decided in Washington, nor should it be.
