See, that's the problem. There doesn't need to be a point. You don't have to win if you don't want to, but I reckon it'd be a bit of fun.
I won't deny that I have had moments where I've felt that there might be some grand purpose or meaning to Life, the Universe and Everything, but at the same time, I choose not to dwell on that, purely because it is an unattainable goal.
"Surely it's attainable," I hear you respond. Trust me, it's not. The endless yearning for a goal that we can't see, explain or understand, is the driving force of the human race. It's the get-up-and-go that empowered our ancestors to invent tools, and eventually reach our current state.
If we could reach our higher purpose, we would have no need to progress any further on the Earth because we would have found what we needed, and not bothered to go any further wahtsoever. Could you imagine if people in the Stone Age had found life's meaning? They surely wouldn't have bothered to invent the wheel or anything fancy like that, because, "What's the point? We know what the meaning of life is."
The search for life's meaning is what keeps us going. Without it, our get-up-and-go would have got-up-and-went a long time ago.
Just set yourself your own goals, and have fun achieving them - enjoying myself is the only purpose I need to exist.
