DON'T STOP WRITING!
Even if you hit a rough patch and nothing you scribble down makes sense and nothing you furiously type is any good never stop! You need the practice, even if it's going nowhere. Keep writing even if it's just little quotes or plot charts or a few lines that lead nowhere. Writing is like every sport in the world, you can't stop and hope to start again and carry all those skills and ideas you had a week ago.
The second point:
Always be prepared. My best ideas have come just as I was falling into sleep or settling in under the covers. At work I would print off receipt paper and scribble in sharpie when an idea hit. So always be prepared. In your purse (or pocket) or in your car keep a pad of paper and a pen or pencil. On your bedside table leave a journal and a pen and a booklight. Always be ready for an idea so fantastic you'll regret letting it go.
