We tend to bury our minds in a never ending constant stream of thoughts. Especially busy people who work a lot. When is my next meeting? What am I going to say on the presentation on Tuesday? Should I attend that dinner tonight? Hmm, I should really do something about this e-mail I just got.
We think thousands of these thoughts every day, with absolutely no space in between, and with no reflection upon the fact that we are doing it. Many people are stuck in this constant flow of thoughts their whole life. I think it builds up stress and inhibits your creativity and inner calm to let this constant thought-loop run your life.
A few years ago I read some books about mindfulness, buddhism and related topics. For example the books by Eckhart Tolle as well as more classical ones such as Zen mind, beginners mind. The books made me realize that we have this constant stream of thoughts, but more importantly they made me realize that it is extremely helpful and soothing to take a break from them. To take a few deep breaths, and create a space of time where you just focus on the present and wave away the stream of thoughts for a few minutes.
If you don't feel like reading books, a great way to get started in no time is the headspace app. Try it for 10 minutes a day and discover how it feels!
