What exactly are the three views?
Worldview
The books you've read, the paths you've walked, and the people you've met make up your worldview. A person's worldview is determined by what they see, hear, and know.
Values
What do you think is right, and how should one act? For example, some believe health is the most important, others believe wealth is the most important, and some believe power is the most important; this is values.
Outlook on Life
After reading so many books, walking so many paths, and meeting so many people, you return to reflect on yourself: What is my dream? What kind of person do I want to become?
Summary
Worldview: is the angle from which to view problems,
Values: is the height from which to view problems,
Outlook on Life: is the attitude with which to view problems.
Your worldview + values together determine your outlook on life.
