What do you think happens after life is over?

Ive been thinking about this a lot lately.. This whole life experience, what is it for? Why do we go through all these things like pain, loss, happiness, sadness, what is the purpose of working so hard just to get nothing much in return? What is all this for? Why are we going through all these emotions and trials.. what happens to us after we die? Id like to think that good people go to heaven and the bad go to hell, but does telling a lie every now and then make you a bad person? And what about everything else, if we make the wrong choice to take a drug or abort a child, does that make us hell bound? Can anyone help ..?
