The meaning and purpose of life is fairly simple.. It is actually quite obvious but it is probably hard to understand until you get a few years under your belt.
And that meaning is colored by perspective, that is, who is trying to define what it is as to you.
Once you get it, it will be like a Eureka moment. And many things that have puzzled you, will reveal themselves.
Look to some of the classical philosophers for hints.
Thanks for the fine article!
