If a trader wants to be super successful he needs to understand that it's a tough job to do, all humans have limited brain capacity and if you waste your brain energy on trivial matters then believe me your capacity to do other things gets affected, including trading
I don't watch much news, no TV no paper, in news paper I mostly read entertaining stuff or knowledge improvement stuff, no politics nothing nada............. My trading room has no TV.
A trader needs to focus on his charts so much that his mind should be occupied in charts related stuff even when he is not on pc, day and night, yes it's initially very much necessary later when trader is an expert then maybe he can relax a bit, repetition leads to practice in mind and it matters,
We are so much occupied in trivial stuff in our lives that we forget what a big giant task we have acquired being a trader, nothing is more important than trading In initial years because initial years are make or break time for a trader, if he did not handle these years and could not achieve success the scars of his failures will not let him grow out of hard ship periods.
To each to his own, this is my personal viewpoint, others may differ
