Although the specific steps differ slightly from person to person and depend on the type of plan you're creating, there are general steps to ensure a good result. The steps in the planning process are:
To plan anything, you must determine what you want to accomplish during a period (a day, a week, the next few hours). A long-term strategic plan might focus on broad achievements that require many steps and skills to accomplish, while a plan for the day might target trying a new method of tracking your hydration or ensuring you get housework done.
Once you have an objective in mind, you must develop a list of required tasks to meet that objective. If you want to ensure you get housework done, what steps are needed? You MUST keep in mind your deficits and make sure you incorporate measures to compensate.
What order makes the most sense for accomplishing the tasks? If you don't organize the steps in an order that will lead to the outcome you desire, you can't possibly achieve that outcome.
How are you going to know if you're keeping on track? How will you remember that you are even trying to meet an objective? This will vary depending on your needs and abilities.
Notice how the planner has specific sections to help you plan your major needs.
This is an example of what your planner should look like.
