"Fate" and "Luck" and "Life"

"Life" and "Fate"
It's life depends on fate?
Somebody paid the same effort like other people,
But the outcome of the effort is different,
How come?
It's "fate"?

And the "fate" is depends on "luck"
If you are lack of luck in your life,
Then your fate is hard..
So, fate+luck=wonderful life~

But,
The problems is:
Where and when my "luck" come over me?
I need you--"luck"!
