The only way to succeed consistently is through planning. And planning begins with organization. Sometimes creative people will say they don't want to be organized. They are wrong. The most creative people are generally the best organized.
Many remarkable artists are almost compulsive in their organization.
It gives them the freedom to be creative. For example, just think about how much more creative time you would have if you didn't waste it searching for your car keys. By organizing, and putting your keys in the same place every time. Believe it or not, it is relatively easy to get organized and to stay that way. We generally have a course outline for any college class, and we make a list before we go to the grocery store, but we often try to tackle a major challenge without the slightest bit of written assistance.
