Catch the right programme on BBC Radio 4 and it's like taking a tin-opener to your mind.
On a wet Monday morning on my way to a humdrum engagement in Dungannon, I happened upon 'How to Play', a study of how musicians come together to perform what they describe as the ultimate test; Mendelssohn's Octet.
Not a classical music buff? Me neither. No matter. This is about precision and practice. What makes the Octet so darned tricky is you have two Quartets, the Elias and Emmeline, performing together.
In such circumstances, eight musicians have to respect the force in which they all play, or else it collapses beneath its own weight.
Violinist Daniel Hope explained how each musician would study the exact weight of their bows on the strings and precisely how long a split second off the strings would be.
Mendelssohn was 16 when he wrote it, of course. When I was 16, I was stressed out with the complexity of trying to nail plasterboard onto ceiling joists as an apprentice joiner.
Although the music side interests me, it was the pursuit of perfection and how it is attained that truly gripped me.
Availability of coaching material and its proliferation through the internet has meant that this information is more widely available than ever before. One element that emerges more than most is the importance of deliberate practice.
Managers have been tapping into this for a long time. One celebrated example was Joe Kernan bringing Dave Alred, Jonny Wilkinson's kicking coach, over to Armagh's 2002 pre-Championship training camp in La Mange to work with Oisín McConville.
While Oisín wasn't convinced that Alred's methods were suitable for his technique, he learned plenty about routine and consistency. Two back operations meant he had to switch to kicking from his hands rather than the ground, but he was able to master the new method through routine and consistency.
Nowadays, that is drummed into young players going through their gawky years on development squads.
All the other various component parts are added in - strength and conditioning, nutrition, sleep, hydration, and tactical awareness by a variety of specialists from across loads of fields.
Gaelic games has become very comfortable with adapting various elements of other sports, such as basketball with the Kerry team of the Golden Years era, and the present day Dubs. Some even go to Mixed Martial Arts sessions.
So why, then, the push back against Dublin's Dean Rock for advertising his services for free-taking lessons?
You can put all the various other elements together and still never be able to measure their precise value. But that's not the case with free-taking.
Nobody wins anything without a place kicker. Along with kickouts, it is the most important role on any team.
Rock's average success rate last summer, as Dublin achieved five successive All-Ireland titles, remained above 90%.
He himself has worked with Alred. In the rarefied air of All-Ireland finals, his nerve holds. In the 2016 final replay win over Mayo, he scored 0-9, 0-7 of which were frees.
One year on, he hit 0-7 again against Mayo, 0-3 of which were frees. The final one was the 'winner' of the game, with Mayo defender Lee Keegan attempting to distract him by throwing his GPS tracker device across his line of sight.
Last year, he was 0.1 off Kerry's Sean O'Shea with an average of seven points per game.
In 2018, he had the highest rate with 6.7 points per game. He had the same the year before, though he was pipped by Cillian O'Connor.
Rock, along with O'Shea and Michael Murphy, are phenomenal place kickers but none of them woke up one morning with this talent.
Some are uncomfortable with a present-day player charging for his coaching services. A sample rate, in case you don't know by now, is €350 for the first two sessions on a one-to-one basis.
Other more favourable rates are available to make it achievable for clubs. Rock is ballsy for taking this chance but will it even be an issue when this becomes the norm in years to come?
A final word. Perfection can never be truly attained in the mind of the creator. Mendelssohn might have been 16 when he composed the Octet, but it took him just over a decade before he would have it performed.
And having Dean Rock coach you is still no guarantee you won't fluff a handy one 21 yards out in a big game. All you can hope for in that situation is that word didn't get out that Deano was up at your club.
