Creativity is just connecting things. When you ask creative people how they did something, they feel a little guilty because they didn't really do it, they just saw something. It seemed obvious to them after a while. That's because they were able to connect experiences they've had and synthesize new things.
Your personal life, your professional life, and your creative life are all intertwined. I went through a few very difficult years where I felt like a failure. But it was actually really important for me to go through that. Struggle, for me, is the most inspirational thing in the world at the end of the day - as long as you treat it that way.
