At the end of a year I usually take some time for setting goals and thinking about possible project for the upcoming year. I do so in 3 steps.
Step 1: Note down goals and projects for the whole year no matter when exactly you're going to work on it.
Step 2: Now sort those goals into the four quarters. If necessary break a goal down into various steps.
Step 3: Break down your goals even further and sort them into the 12 months. I recommend doing so quarter by quarter. Mostly planning a month in detail about a year in advance will not work out. So around the beginning of March sit down to map out your goals and projects for April until June and so on.
I love to have my lists of goals handy all the time therefore they're part of my planner.
