Difficult != time consuming

There. I said it. Difficult problems are problems that lack a solution. Problems that can be solved, problems that have many existing solutions today, are not difficult. Not all problems are difficult, but they are time consuming and it would be preferable if they could be solved by someone else. The problem with such a solution is that things change, and when you rely entirely on other people for your solutions, you'll lose the ability to adapt in a situation when your out of the box (component) or solution can't sustain your domain. That's why you sometimes have to do things yourself, in your own way. Because no one else understands your problems that well.
