Depends on what you mean by luck.

If you mean waiting idly wishing that a particular event would happen in this world, then no.

If you mean taking the same event that happened, and finding how to find ways to make the most out of it, then yes.

It is always about luck, not one you wish to receive from the outside, but one you create from the inside.

Exactly!

I'm sitting here in my sofa, and luck still didn't struck me. Still not a billionaire :(.

;)

Both, I'd think. It's ultimately up to fate or luck or other such thing, but in the meantime you can make moves in hopes of improving your odds.
