Values and our lives purposes

Have you ever thought about your life's purpose? why are you living in this world? what are you living for?
Difficult question, ha? It's more likely to ask why are you breathing? Seems we have taken our living for granted! In most of the time we set goals and start to get going towards it, but at the middle of the way , we start hesitating, IS THAT THE RIGHT WAY?
It's very similar to the situation when you devise a trip and don't know where is your exact destination......you may proceed to the nearest city but where to go after it?
When you don't have a specific map,it's not easy to keep going, each moment you may think of whether you are in the right way or not..
So how to make sure of being on the right track?
GOOD QUESTION !!!
Just take a look at what you've done and been fulfilled by it....what is most remarkable on them? What has made you satisfied ? What is common pattern between them?
Is that possible that you have been following goals that were based on your values and that's why you've been fulfilled?
What if you get clear on your values first then enlighten your purpose of life?
