Can anyone give me a clear and concise philosophy on Life?

I hope this isn't too broad of a question but I've been searching for everything from a purpose to an explanation on to how to behave to what my perspective should be. I want to be informed on how to interpret the world. I've looked at religion but it doesn't make sense and I want to be convinced. I'm not asking for a self help book to show me how to be optimistic, I'm asking for a philosophy that explains how the world works and how I should behave. I've read all of Hobbes, Rousseau and Machiavelli. I'm still really confused.
