...Instead of "I can't, because...", "I can't, because...", "I can't, because...", why not reframe the question in terms of How -- "How might I...?"
How constructions are usually much more productive than Why constructions, at least in my experience. Why questions seldom have answers. How questions at least impose order on chaos.
So true.
