Theories, views... is it about me?

I used to be asked about my personal philosophy and points of view on many life-situations. I've never been good in answering such questions, 'cause i think every situation in your life needs special decisions and points of view, everything depends on situation. 

I always thought myself a person with an indefinite amount of principles, but now I don't want to limit my decisions and actions with theories which have no proof. There is only one thought which I use to follow. I think that during our lifetime everyone encounter with his lifeline, it may be everything, for example, a person you get to know to, an action or decision to make, something that can change your life or point of view on something, but usually it doesn't even change anything, it just makes you more experienced and tempered about life. I used to call it "lifeline" just like in my favorite song. A lifeline is something that life gives us to follow and to chose, we are to decide which one to not to let go.

For example, one of my lifelines got me here for blogging and writing, so I'm trying not to let it go.
