What do you write down? For most of us, writing consists of emails, task lists and perhaps the odd work project. However, making time to write down certain things, such as our daily experiences and feelings, can help us in our life.
The following are some different ways that writing things down can change your life.
It clears your mind for higher-level thinking.
David Allen, productivity speaker and author of Getting Things Done, recommends doing what he calls a “core dump”. This involves writing down every task, activity, and project you need to address. This could range from picking up milk on the way home, to a multi-person project at work. Writing down every ‘to-do’ item you can think of clearing space in your head for more important topics.
It helps you process your emotions.
Writing down what’s on your mind is a great way to work through inner conflict or process your feelings around a particular situation. It’s similar to talking a situation through with a friend, and it’s a useful way of strengthening your self-soothing (自我安慰) abilities.
It gives you a record of the past.
If you keep a diary and regularly write down your thoughts and feelings, you’ll soon have a record of your experiences that you might otherwise have forgotten. Keeping a diary can also enhance your levels of self-trust. When you can look back and see how successfully you’ve done in the past, you’ll feel more confident in your ability to do so in the future.
You gain a sense of achievement.
If you write down everything you need to do in a particular day or week, you gain an additional sense of satisfaction. When having completed the task, you can cross the item off our list. Feeling productive enhances your productivity and fosters a sense of achievement and progress.
