Writing software is hard. Depending on your perspective, this can be a good thing or a bad thing. I once had a colleague tell me that he was glad that writing software is hard because if it wasn't hard, then anybody could do it, and if anybody could do it, he would not get paid as well. If you are on the management side of the equation, however, then the fact that writing software is hard is not such a good thing, because that means that getting software written can be expensive.
