For me that has led me to the purpose of learning and teaching.
Before I became a teacher I was a marketing executive (and also, while studying, a bouncer), but I am much happiest in a classroom full of pupils.
Of course, one should be prepared to make sacrifices in order to reach one's goals, and for me it took a lot of work and a substantial cut in my paycheck.
But I am much more satisfied with my life now than I ever was in my old job.
This purpose is different for different people and what makes me happy might not make the next person happy.
For some it is music, or writing books, or designing things, or raising kids, or any number of things that may or may not be job related.
The point is that finding out is part of the journey and a goal in and of itself as you grow as a person.
I don't hold to the notion that humans have some overlying cosmic/magical/divine purpose or meaning to their lives.
That sounds a bit too much like 'woo' to me.
Sorry.
