Why is life so confusing?

This is something that is a topic that almost every human has issues with, whether it be past present or future. So why IS life so confusing? I really truly wish i knew the answer to this. In fact we all do! I think in the end life is confusing simply because if we already had all the answers we would gain nothing from life. We would never make new friends, we would never fall in love, we would never have many of the experiences that makes us each who we are as individuals. That's why life has to be so confusing.
