Personally, I think intuition can be sharpened and expanded through meditation, diving into the Self. There's an ocean of consciousness inside each of us, and it's an ocean of solutions. When you dive into that ocean, that consciousness, you enliven it.
You don't dive for specific solutions; you dive to enliven that ocean of consciousness. Then your intuition grows and you have a way of solving those problems--knowing when it's not quite right and knowing a way to make it feel correct for you. That capacity grows and things go much more smoothly.
