I think I would call it more opportunity. if you're in the right environment and yes, work hard opportunity will present itself. Would you consider opportunity luck?
I've had clients want to invest in my gym because they see the success I've had and yes, how hard I work at it. Is that luck or opportunity?
It really defends how you define luck. In this context you may think that luck suggests receiving something with out working for it, like winning the lottery.
I think we do get lucky when presented with some opportunities, but that is usually because hard work put us in the right place at the right time.
Like Bill Gates for example. He slaved away at coding for years. One day IBM came knocking at his door because the people they were in town to see first weren't home. He seized his opportunity. Was he lucky that the other person wasn't home or was it his hard work? I'd say both.
In your case i think its 100% hard work on your part.....But not in every case and luck has had a part in some people's success. However, rarely is it all luck and no hard work.
