When you have goals, you are less prone to clutter of the mind and existing clutter is easier to eliminate.
Write down all your goals.
Now separate them into long term goals, mid-term goals and short-term goals.
Find out a way to incorporate your goals into your daily life.
Let’s assume one of your goals is to write a book. You can incorporate this into your daily to-do list. Perhaps you commit to writing 1000 words each day with your morning coffee.
Make sure to set realistic goals. If you have a weight loss goal and can only lose 2 pounds in a month, don’t set a goal to lose 8 pounds in a month. This will only add more clutter to your mind.
