Explain in detail the meaning of the preamble to the constitution. give one example of how the preamble has affected your own life.

We the people of the United States in order to form a more perfect union establish justice, ensure domestic tranquility, provide for the common defense, promote the general welfare, and secure our blessings of liberty to ourselves and our prosperity. Do ordain and establish this constitution of the United States of America. 

It was necessary I write that down before explaining, though I also know that I have written that down off of memory, and so there is a chance that some of that could have been slightly wrong or mixed around.

Either way, the meaning of the preamble was to right off the bat explain exactly what the intended purpose of the constitution was supposed to be. The United States of America was supposed to be a "together" sort of thing. A "we" situation. They may have gained their freedom, but they were still messy, and the government of that time hoped that this would be something they could provide for the people. They wanted to let the people know that they planned to ensure peace throughout the country, work hard to keep their military up and in top performance to protect their people with, and make sure that people were able to claim and own their own things with this freedom, and that they would not have this new liberation stolen from them. They hoped that these promises would help better their new country and make it something everybody could live peacefully in. Do ordain and establish, for example, was meant to secure the idea that this was a new nation and that it was concrete and there to stay.

An example to mention about your own life could be how maybe the preamble makes you feel safer under such promises or that because of the security it helped make the people feel, it influences you to make promises you can keep under pressured situations. If two friends are fighting, maybe you now know a little bit more about how to try and cool things down. Perhaps you now know a little bit more about how strong "we" really is. The example is really something that is more personal than anything.
