Do you clear your minds daily?

I must admit that I am a very distracted person. I have done well academically but I could have been great if I was not so distracted and wondering about things all the time. I got into a lot of problems with this especially when I was working construction. I read this article about mindfulness and its techniques such as deep breathing and increasing sensitivity without allowing your mind to wander. Do any of you have the similar problem that I have and do you practice mindfulness daily? How do you cope with an overactive imagination and over thinking?
