I think for each person, that answer is going to be different. For me, it's happiness and love. It's being with the one person who is truly my other half....makes me complete....fills me full of joy with the sound of his voice. So my answer to "life" is him.
Could we have the question? Then you may get the answer.....
There is no such thing as "the answer" to this question. Since we have a limited amount of time to enjoy it though, I recommend finding out what you enjoy doing and doing that as often as you can. When I was younger and more naive, I used to believe that there would be some sort of map to follow that would be created for us to follow by some higher being. Now, I don't want to come off as a religion-shamer here; far from it.
My point is, since there is no such thing as "the answer," it would be a good idea to explore new things (if a religious life is right for you, go for it! If not, fret not!). I suppose "the answer" could be that since there is no "answer" all one can do is go on a life-long journey to discover one's purpose.
I don't really think there is an answer. The answer is what you make of life, how you life your life and what you do while you are living. It's a mind set, choosing to be the best person you can be and one day dying knowing you had a very successful life that you lived. Whether it was adventurous, or being a mom, it is what you make of it.
Old question, but i'll say 42.
