The worlds a stage- William Shakspeare

This quote has different meanings and interpretations. I must say I agree with it. This quote to me means that people can play any role in there life. They can lie throughout there hole life, they can choose to be themselves as well, and there you create a character, a character on stage, and i think in this quote the stage represents life. Life is the stage, and you will choose how to show off your character, because really when we watch a play we discover who someone is acting as through his/her actions. And the actions in real life you represent yourself with will tell people who you are.
Another interpretation that i made is, plays that are played on stage are a series of events, just likke our life. Our life is full of "stages (lives)" that are different, and thats what i think this quote is trying ot tell us. We go through various stages in our life (infancy, childhood, love stories, education, soldier, justice, old age, etc.)
Also another interpretation on this quote is, manipulation. There is a lot of it these days, and it always existed, and always will. What I am trying to say here is that human beings are now treated like puppets, and are manipulated to do things they are not wishing to do, as if it were a human puppet show.
I think this quote applies to everyone, that is why i like it, everybody has different stages, and different changes observed or noticed by others whether the "actor" thinks there alone or not.

The end justifies the means

Doesn't matter what you do as long as the outcome is your wished result. This quote is not always true. Because it can be covered as both good and bad things. the final outcome becomes the reflection of your earlier acitons. For example, if the goal your trying to achieve are negative, you should not try to approach it that way. This qoute does make sense, and is true, but it can be considered as both positive and negative.
The person who wrote this quote was Machiavelli,  a man that was very negative about liufe, and believed in fear and hate. Based upon this fact we can say that this qoute cannot be placed as a ALL- situation quote.

Outer Beauty is the True Sign of Inner Goodness

I strongly disagree with this quote because your outer doesn't reflect the beauty you contain inside you. Outer doesn't reflect on your character. Outer beauty is something your born with. And character is something you choose to be, and someone you want to be. You can choose to be nice to someone, or mean to certain people, but you cannot change you outer beauty in any means (in those days at least). You can change you outer beauty, but the inner goodness is the true sign of beauty. The beauty you have inside you can make up for the outer flaws.
