Useless.

If you decide to critically think about life, you've got two options. You can either think about it from the perspective of you as a person on this world. But you can also think about it by using the perspective of something bigger outside this world, that watches humanity grow from afar.
Through the first perspective I see that humanity is important. We all live. You can't change that very easily. So you've got to make life the best you can. You've got to enjoy life to the fullest. This can be done by materialistic stuff but also by love, friendship, encouragement, success etc. It's all part of your life. It doesn't last for long so why would you just sit around and do nothing, while there are so many goals you can try to achieve at the same time? So many things you know you want. So why not go after it? Now is the chance, because now you're alive. We all need to make the best of it, we all need to be happy.
But on the other side.. Through the second perspective I really start to think seriously.. You live, you're alive. You do things in that 'life'. You achieve goals in that 'life'. You get children. You give them love. They give you love back. And then you die... Then what? I mean.. Life goes on without you. Of course people will miss you. Of course people will cry and need time to get over the fact that you're gone. But life still goes on, the world really won't stop turning. The rest of the world is still alive. They still do things in their lifes. Like nothing really happend. Because why would they miss you? It sounds mean, but it's true. Everybody makes certain goals that only have an effect on their children, grandchildren, family & friends. It's actually pretty selfish, even though we all do it and don't really notice that we do. Those goals are only small goals. Small goals if you look at how little it has an effect on. Why can't there be one big goal that has an effect on the whole world, on humanity? Why is there never an effect that lasts for ages? A goal that changes the way of living by humans. Nobody can make a goal in their life like that. Not me, not you. We just live for ourselves and the ones we care about.
Also.. What if humanity never existed. Would there really be something missing in this universe? Our existence doesn't have anything to do with the universe, it doesn't have any effect on it whatsoever. We get born, we live, we die. It just keeps going on and on and on like that. So if we wouldn't exist, whatever there is in the universe wouldn't miss us. We're useless. Humanity is useless. Everything we do in our daily life, every goal we make & achieve. It's all useless.
My conclusion now is that at this moment, you're alive, which means that you have to enjoy the fact that you're breathing. That you can be where you are. That you have people around you who love you, who care about you. You should do anything as long as it will make you look back when you're old and think: 'My life was great.' But if our spirits still exist in maybe 10 ages. Which means we've seen a lot of people get born, live and die again. Which means we've seen a lot of goals made by humans that only had an effect on a small group of people in a short period of time. If our spirits still exist by then.. That's when I think we'll look back and think: 'Our lifes were useless.'
