To create an effective task list that will help you achieve a goal, you need to start by thinking about what you want to achieve and what activities can lead you to achieve that goal.
Once you have thought about it, it is important to take a paper and write down the goal to be achieved and the tasks that will help in this process. This need not be done necessarily on paper, it can be typed on the computer and even on the cell phone, the important thing is that you write, because it allows your brain to understand that this objective is no longer an idea and has become something concrete and substantial.
Start by writing the tasks that will be easier to do and increase the degree of difficulty. You can set a date for each task, so that it serves as an incentive to complete it, but if that increases your anxiety, you just leave a date to reach your goal, which can even be a long date, since each of us works in his own time.
Leave the list on a visible link so that you always have the tasks you need to complete in mind.
