Kenyo finds a mission

I just finished reading a book: Kenyo finds a mission a few days ago. It's a a parable about Kenyo, a young donkey who searches for meaning to his life. Although it could be categorized as children book, I think the adults still could enjoy it. When I read the synopsis, I didn't think something special Kenyo, but when I reached the middle chapter, I started to guess who Kenyo is actually.. and it is like what I thought.
He is indeed a special donkey, who thinks that he has no purpose in life but then God shows him that he has a big mission in his life, just like what his grandfather did.
So in the end, yes, Kenyo finally finds his mission.

Speaking about mission, I'm still not sure how we could know our mission.
Have thought about it several times in life, but still no clue.
Is it something we go after or is it something given?
From Kenyo's story above, it's like something given (by God). But how could we recognize it? hmm

Nevertheless, we'll perhaps just try to set our mission until He gives us one.
How about helping other people reach their dreams?
Sounds heavy.. but we could start from something.
For instances: to let mom and dad get their dreams (something they never did or had because of us), to let someone focus on his dream for having a company and retiring at 35, to sponsor a child, or to help someone finding his soul mate =).
Or being a surrogate mother. I was thinking about that when I heard someone close to me having pregnancy problem.

But hey, everything is possible in our mind.
The next important thing is how we're going to do it.
