I waste too much of my time in wasteful thinking. Can brainwave entrainment help me?

Answer 1

Maybe. There are programs you can buy that use different levels of brain wave stimulation, that also include settings for things like concentration and focus, I have one called Natura. You can find it at http://www.opticalsweets.com

But regardless of what a program may or may not be able to do for you, you still need to find the discipline to apply it daily. :)
