Thoughts Happiness

What is the secret of pure thoughts, like when you were a child, and happiness and acceptance?
To be happy and accept things that have bad thoughts, I know how to get the bad thoughts in my head.
The secret of so-called "pure thought" in order the pursuit of happiness and acceptance is to deconstruct concomitant thoughts and emotions and neurotic behavior until the mind and emotional states focused and quiet (no thoughts or ideas attenuated [see the response of Mr. Premaholic of]). Although or because he was too smart for my own good as a small child I have no recollection of having "pure thought" or a high degree of happiness or acceptance at that time. The result was that lots and lots of thoughts assistant and emotional discord. I overcame it with effort. Now my mind is often very clear and calm (ie, "pure").
