You need enough sleep. You need enough sleep in order to function and so as to restore and rejuvenate your brain and your body.
Tens of millions of people suffer from insomnia and other sleep issues. It’s very common that people toss and turn all night or sleep too few hours or not sleep at all. This may often be attributed to one’s mind continuing to focus (at high speed) on issues instead of shutting down at night and resting.
I had a job that required me to function in an extremely high level, always, all day long. By 7AM to 7PM. I could not go to sleep at night because my mind was racing, reviewing the day’s work (and difficulties ) and planning the next day’s work (and difficulties ). The lack of sleep began to interfere with my ability to function on the job at the required high level. If this continued, I wouldn’t be able to do my job effectively and I would soon be tired, and fired. I needed to get more sleep.
As soon as I realized that it was my mind that has been keeping me awake until 1AM – 2AM, I decided I needed to do something about it. How can I solve the problem? What I did was make a bargain with my mind. The deal was that when it was time to go to sleep I would take all my problems, worries and anxieties out of my brain and put them down on the nightstand next to my bed. I promised my mind that all my problems, worries and fears would still be there on the nightstand in the morning when I woke up and I would pick all my problems up off the nightstand, place them back into my brain, and my brain could start spinning and rushing and worrying all over again. After a few nights of trying this it started to work. I fooled my mind. I trained my brain. Now, when it was time to go to sleep, I was able to put down, put my problems and worries and anxieties aside, and go to sleep. That was decades ago and ever since that time, when I get into bed, I put down my troubles. And have no trouble going to sleep at night.
In addition, I learned something else; a lot of the things I worried about at night vanished or diminished when I went to pick them up off the nightstand the next morning.
When it is time to go to sleep, the day is finished. Place your worries down. When day is done and it’s time for sleep, there is nothing more you can actually do right now about your present problems, worries and fears. Put them down on the nightstand, or, if you want, put an empty box beside your bed to put your problems in at night. Do not worry, all of your problems, worries and fears will still be there in the morning. Or not.
And, if you wish, you can even write down your worries on a piece of paper and physically put them in the box. Or not.
As for the box, any empty box will do. Any color. It may help if the box has a lid and you may leave it open to readily put in your worries, problems and anxieties. No, it does not need to be a large box. Unless you have a LOT of worries.
