I absolutely love the house of cards analogy. A mistake we make when it comes to our identity is defining ourselves in terms of what we think or been told that we are good at instead of what we love to do.
I am good at academics, I am good at basketball yada yada. It should instead be I love studying, I love playing basketball etc.
As to being mediocre, there is no one mediocre. You can be mediocre in one thing and extremely talented in another. We are all gifted, it's just that the gifts happen to be wildly different.
