No thought is worth more than mental discipline. In other words, any idea or mental-image currently capturing your attention is less valuable than a well-focused mind. A thought will never provide the insight or satisfaction that mental discipline brings. This means it’s better to specifically direct your attention, instead of allowing it to wander amongst thoughts.
If you dismiss a thought, you’re not missing anything important. Thoughts come from a chatterbox that likes to hear himself speak. But he rambles on until he stumbles into a topic that thrills and excites, then you’re stuck with the resulting anxiety. You do yourself a favor by stopping this process and preventing this search-for-excitement.
This chatterbox is like a hacker brute-forcing a way towards anxiety, trying every combination of ideas and images until he finds a weak-spot into your attention. And once found, he throws everything he’s got at it. Deny such attacks by shutting down the spam, don’t bother looking at the attention-getting titles, just auto-filter it out.
This chatterbox is like a door-to-door salesmen that constantly comes knocking – don’t invite him in or you’ll be subjected to a stream of solicitations all day and night. “Boredom!? Not any more with the new and improved Thought-o-Matic Instant Anxiety Machine! It’ll make you tremble with stories so shocking, that you won’t be able to concentrate on anything else!”
Mental discipline is the practice of not answering that door. It’s the practice of denying thought-scans that seek surges of emotion. It’s the practice of putting proper focus first, above all thoughts. So stop giving thoughts priority, put them in their place below mental discipline. A well-focused mind is the key to your satisfaction.
