Answer:
I believe that we all have a purpose, some of just not found it yet. Look at it like this, we humans are like engines, and purpose is what fuels us to run. The better the purpose the more powerful we tend to be. Not all purposes are good, and that's why we have the police. Their purpose is to take care of those with a bad purpose. "Why is my purpose?" Is something you will ask yourself a lot in this lifetime, and I believe that the easy way to find it is just by living your life and doing what feels right.
