If you are trying to shine everywhere and for everything, you are just a self-fish, self-absorbed individual. But if you try to only shine for what you can offer best to the world, then you are responding to your call and leaving room for other people to have theirs.
When it’s your turn, shine like a star. But when it’s an opportunity for others to bring their bests, help them as much as you can and enjoy while they are shining.
