I think my main problem in chess is I lose attention. I catch myself sometimes with my mind in other places, and when I stay tunned, I am not enough focused on a reasonable inner thinking method, but rambling about what comes to my mind.

How do you train attention? how do you do to follow a reasonable thinking method? any tips on how to improve this problem?

You point to a problem that many of us share. And it's not just a problem with losing concentration; sometimes we can concentrate too hard, and miss what is right under our noses. We can be calculating variations furiously, but overlook the fact that our opponent's last move allows a simple mate in two. The great Frank Marshall once said that "In chess, attention is just as important as concentration." While C. J. Purdy always admonished his students, "Don't just look ahead--look around!"

I don't know of any miracle cure, but you will help yourself immeasurably if every time it's your turn, you first quicky look at the board and assess every check, capture, or threat that your opponent has available, and decide if you need to meet any of them. Next you examine every check, capture, or threat that is available to you, and see if any of them lead to an advantage. This doesn't take very long, but if you faithfully carry out this process on every turn, you will both keep you head in the game and avoid a lot more of your opponent's tactical threats, while carrying out more of your own.

You'll win more often!
