First, you may want to make a second post in reply to this, which has all of this content. The moment this (or any) message is posted in reply to your original, it'll be edit locked.
Secondly, there's a lovely parable I think is worthy of the occasion, I can't remember where I heard the original, so this is my reconstruction of it.
A Westerner goes to Japan
A Nihon-struck westerner went to Japan to learn the exotic ways of eastern swordfighting. The beauty of fighting with a Katana had appealed to him ever since he once caught an Akira Kurosawa movie on late night cable while he was channel surfing for an entirely different sort of riposte and parrying. The elegance of the combatants inspired him, their movements held a grace and beauty he felt long lost in his humdrum life, a tear escaped his eye and trickled down his chin as he was enamored by it all.
The Westerner knew what he wanted from life, and built up enough savings to see him through a year of lessons in Japan. He eagerly applied for and received a visa and took a year off from his job. On arriving at his dream country, he suffered a temporary period of heartbreak when he realized that the real Japan was nothing like the movies, but still soldiered on and joined a dojo with a renowned master.
The Westerner was a diligent student and eagerly abided his master's wisdom at every opportunity. With no other commitments to weigh him back in life, to burden his mortal coil, he dedicated himself fully to the way of the katana. His skill with the blade grew quickly, and after a month he was performing better than half of the students who had joined with him, and in this knowledge he was happy.
Unfortunately, the joy was short lived, after another couple of months his performance had slid down to the weakest ten students in his group. The westerner was confused and alarmed at this reversal of fortune, but nevertheless, being an optimist he didn't lose hope. He doubled down on his efforts, cut back on traveling the countryside, and spent every waking minute practicing his form. His master (Sensei) was supportive of his newfound determination, and would give pointers from time to time. Unfortunately, the student's form was stuck, and it wasn't improving. Another three months passed, and the westerner was the weakest of his class, bar none.
One day, after mind-numbing frustration and rage at his own impotence, the westerner approached his sensei, distraught about his abject failure to learn. He had the following exchange with his Sensei:
Sensei: (Who noticed the Westerner's shuffling arrival, turns and faces him, and begins in broken but comprehensible English) I have noticed you have trouble learning the way of sword, am I correct?
Westerner: (Distraught) Yes Sensei, I've tried everything! Everything! Please, Sensei, guide me!
Sensei: (Calmly, like a gentle father would talk to their own son) Alright young one. When you are practicing form on cliff by beach, do you notice gentle movement of the sea?
Westerner: (Enthusiastically) Yes Sensei! The gentle waves remind me of my place in the world, they remind me to flow like water!
Sensei: Good, and you notice the birds searching for food, flying above waves?
Westerner: (Even more eagerly, delighted at his Sensei's understanding and his own competence) Yes, I do! I notice their feathers moving elegantly as I practice my chops. Their effortless dives and determination remind me on the need to have determination!
Sensei: (Stroking his beard) Excellent, young one. Do you notice blades of grass stirring as you practice?
Westerner: (His delight can barely be contained, he speaks with unfettered glee) Absolutely Sensei! I feel one with the earth and heavens, I feel the motion of each moving blade, as the gentle wind blows! I can see the cherry blossoms in the distance, the sun in the sky, the glow of its rays bouncing off Mount Fuji, the... (at this point Sensei interrupts his reverie)
Sensei: (Adamant, and frothing with rage) You imbecile! No wonder you fail! You focus on everything except what's important!
Moral of the story: Stick to one thing at a time for best results
