Be determined to get where you want to go. Writing is a tough business. Learn to develop a thick skin and roll up your sleeves and get busy. It's important to continue to publish new works. You just can't publish a few books and go on vacation for the rest of your life or forever and be a successful writer.
Develop some writing goals; daily, or whatever suits you. Writing goals are what keep you productive.
Come up with a new story idea. Revive some of those stories collecting dust under your bed.
Start writing again. Jump on it!
