I don't think life has a point.
Biologically speaking life is it's own purpose, and your only job on this planet is to stay alive and have children, so that your lineage will continue after you're gone.
Personally, I don't even think the biological purpose fully applies. While humans are still bound to many primal instincts (more than most of us think), we're often able to take a step back from them. An example here might be people who make the conscious choice not to have children, or who choose to adopt rather than create their own offspring.
So while technically our purpose is no different from that of any other organism, on a more personal, philosophical level I prefer to think that life doesn't have any point, goal, or reason. Sure, you can strive to be happy or to make others happy in a million different ways, and those are certainly Good Things, but there's nothing saying that that's what you're supposed to do. I think that life itself has no meaning, because that leaves you free to find your own meaning. If you find meaning in helping others, that's great. But if you find meaning in earning as much money as you can, that's just as good (in this context, at least). If you don't find any greater meaning at all and are content in just living your day-to-day life, again, that's just as good an answer as anyone else's. The point isn't to find the 'right' way to live, but simply to live your way.
No reason to live, but I like it that way.
