The view of life - part 1

This is a open question. I would like to invite everyone who read this post to share your thoughts. ( Well, I assume no many people will actually read my blog, but if you do, please give the inputs)

Although I am not an absolute atheist, but as almost all Chinese in my age, my education background roots on it.
So, I try to generalize the opinions about life for my generation. First of all, let's assume God doesn't exist, and the world is purely objective and as exactly explained by science.

So, what's the goal of the life and how should you go over it?

There are generally two answers in my generation.
1) Better yourself, set a goal, and go for it. Always strike and work toward your goal, better yourself throughout the life.
2) fulfill our desires, physiological levels and higher levels.

However, for the answers above, Can you tell me what's the next after you achieved your current goal and desire? Are you really satisfied after accomplishing that?
If bettering or desires are the means of life, what's the end?
If they are the end, then as you know, they will never be the end, because there are more to better and more desires to fulfill. And physically, the end of the life is death, no matter how much you had better yourself or fulfilled your desires, it's no difference when it comes to death. In other words, If they are the end, then they will never end, so why would you bother to start?

Please, any thoughts?
