Next time you think someone’s lucky, remember there’s no such thing as luck, it doesn’t exist.
Of course there are those that are born into wealth, survive death defying accidents, born with good health etc, but that isn’t luck, that’s good fortune.
If an opportunity arises and you take advantage of it, some will see that as luck, you were in the right place at the right time, but you know that you’ve likely worked very hard to be prepared & be in a position to take advantage of the opportunity when it arose.
So luck is being prepared & being in a position to take advantage of an opportunity when it presents itself, it’s that simple.
