You can't do goals, you can only do tasks, so create a list of tasks which will take you to your goal. You may not know exactly what your tasks should be, but as long as you can think of ONE task, you can start working toward achieving your goal.
For example, perhaps you want to write a book. Writing a book is a huge project. Let's say that you set a deadline of one year for the project's completion. Now all you need to do is to create some tasks. Your first task could be: write an outline.
What do you want to achieve? You can achieve anything, as long as you set goals for it.
Few of us set goals. And if we do, we usually fail to follow through on the tasks which would lead us to the accomplishment of those goals.
Set ONE goal today. Plot your tasks... And do at least two tasks.
