It's a tall mountain of achievement that you're attempting to climb. Sure, it would be nice if you could get a free ride to the top, but then you would miss out on all of the wonderful learning experiences as you climb your way up and earn your place at the top. Besides, you'll need those experiences to help you perform well when you finally do reach the top.
It wasn't luck; it was hard work that got you here. While other people might think that it was luck, you know better. It's ironic, but the harder you work the luckier you get. Of course, you know the truth: hard work and effort bring opportunities and new possibilities. The people who think that it was luck don't really understand how hard you had to work for it.
There could be more to this opportunity than meets the eye. Investigate further before you dismiss it.
