Notice how the design on the wood is. Notice the colors of the walls near you. Notice the people near you and the clothes they are wearing. Notice the expressions on their faces. Notice the floor near you. What is it made of? Is there a design on it?
Just look around with the curiosity of a child for some time. Come on, when was the last time you just looked around and noticed things without any reason?
As you do this...some thoughts may creep in. As soon as you notice you are thinking of something, let the thought go and come back to the present moment. Again – look around...and observe things you may never have observed before! Sometimes, I use this technique when I go to dine at restaurants. I notice the tables and chairs. I notice the walls. I notice the paintings. I notice the clothes the waiters are wearing and I notice the expressions on the faces of people. If you do this for just few minutes, you will feel joy. It might seem irritating at first or maybe even foolish. But do it anyway and the irritation and thoughts will vanish.
Soon, you'll think: “Wow. I never knew there was just so much to notice around me.” Repeat this activity as many times in the day as you want. If you do it often enough, you will actually feel like a world of wonder has opened up. This is because generally we are so lost in thoughts that we hardly look around and notice many interesting things. The reason this activity works is also similar to the reason the first one works: it brings us back to the present moment for some time and helps us release our common negative thought patterns. So, well, why not try it right now? :)
