What do you do when you are tired? Sleep? And if you don´t feel like sleeping? There are activities that at the same time that are producing something, help you to relax. When writing freely about whatever topic you are interested or when inventing something related to one of your favourite topics you can fall in a type of flowing experience in which the concentration at the same type is relaxing you, re-energising you with the pleasure of thinking.
During the process of thinking there are some activities such as going for a walk, washing dishes, having a bath or shaving, or doing some house cleaning that can be done without much mental effort and promote the step of incubation, in which without trying to generate ideas, there are thoughts that appear in our mind.
On the other side, there are times that we can try to relax without thinking about anything and is when thoughts come to us. That is why is good for relaxation to concentrate in something such as our breathing, some image or sound, or counting; doing something that doesn´t require too much effort but that keep our minds settled.
There is a simple activity I used to do sometimes that consists of writing one sentence (the same sentence) several times without thinking too much about it. It is interesting that when writing something we can change the speed we write, the quality of the writing, the size, the spaces, etc. and trying to write it with better handwriting can take us away from the meaning of the sentence, even though our brain continue keeping it in the back of the mind. And this sentence can be a question, or anything else.
We are used to input a lot of information with our mobiles, internet, newspapers, etc. and the absorption and digestion of this information in the same way as the digestion of the food can make our body to feel tired. In the same way as fasting can help to heal the body, reducing the information overload, can help healing the mind and the emotions. And the same way as exercising the body, exercising the mind helps to keep a healthy body. By doing physical activity we can at the same time relax our mind and generate ideas.
When we are tired, still we can think and generate ideas and these ideas can be different than the ones we generate when we are not tired. Besides, for some reason, when I generate ideas and when I write about them I feel re-energized, what is a very good tool to be aware of.
