If spirituality is some attainment, then of course it is going to be difficult, not only difficult, but really impossible. If you are not spiritual, you cannot be, you never can be, because how can one who is not spiritual be spiritual? If you are not divine already then there is no possibility. And no matter what effort you will make, effort made by one who is not already divine cannot created divinity.
But the whole situation is totally opposite, you are that which you want to attain. The end of longing is already there, present in you. Here and now, this very moment, you are that which is known as divine!
