One of the first Keys to answering this question rests on the following questions. The fundamental answer to this question comes primarily from your worldview.
Your World view comes from the following:
Where did Life come from? (origins)
What does it mean to be human? (identity)
What is the purpose of life? (meaning)
How should I live? (morality)
What happens after I die? (destiny)
Your world view is not a list of beliefs but how and where your heart is oriented.
Also unlike a list of beliefs, worldviews for everyone is not set in stone but ever changing.
