CS Lewis, that well-known bard of east Belfast, once said, famously: "You are never too old to set another goal or to dream a new dream".
A simple enough philosophy which many of us, occasionally, can remind ourselves of.
And in the case of another, more contemporary, heralded son of rural north Antrim, Steven Davis, this is a credo he has been following in recent years.
Between the Northern Ireland captain and Allan McGregor, they have a combined age of 75. Invariably clever and streetwise, this season, their contribution to Rangers' cause has been immense.
What additionally appears intriguing, in a week where both the Light Blues and Celtic are seriously exploring the idea of their colt teams joining the Lowland League to principally 'toughen up', it is the veterans who are contending for the Scottish Football Writers' Player of the Year accolade.
Davis and McGregor are part of the Ibrox 'fab four' alongside captain James Tavernier and central defender Connor Goldson, with no nominees from other clubs. This isn't altogether a surprise considering the 23-point chasm between runaway Rangers and calamity-struck Celtic. There are many who would be happy for sensible, grounded Davis or goalkeeper McGregor to win the award, the latter for his Old Firm displays and Europa League exploits in particular.
Nevertheless, it is testament to the kind of daily dedications, nous, and flinty character of the pair that they are at the summit of the Scottish game both as individuals, and as part of this robust Rangers collective. Imagine, somehow, the straightforward act of faith suggested by Lewis as fuel to drive on players savouring a clichéd, if entirely accurate, Indian Summer of their careers.
Gers chief Steven Gerrard is an exponent of tough love wherever necessary, but it's hardly a stretch of the imagination to note his observations of both Davis and McGregor in training will be minimal. When committed operators possess such drive towards solid and incremental improvements each day then, for a manager, they are low maintenance. A dream to work with, essentially. The "unfinished business" at Rangers Davis spoke about when extending his stay in Glasgow to at least next June motivates.
Gerrard, now three years in the hot seat, admitted earlier in the season that Davis is even more the model professional than he realised from playing against him for Liverpool when the Cullybackey native was at Southampton, and whose habits, beyond the scope of match day itself, are a stellar example to younger players, like Nathan Patterson, aiming for regular first team action at Ibrox. McGregor, meanwhile, having retired from international duty, could easily turn out for Scotland at Euro 2020 if he so desired - and his manager did not hesitate to place him in the 'world class' category when the goalie also agreed another year's contract.
Out of all the moments of top quality exhibited by Rangers in 2020-21 - Kemar Roofe's wonder goal from the halfway line at Standard Liege in October; Ryan Jack's stunning volley which felled Kilmarnock; Alfredo Morelos' equalling Ally McCoist's European goals total and Ryan Kent lashing home in a dramatic win over Royal Antwerp, to name a few - McGregor's sensational goal line save to deny Slavia Prague's Lukas Masopust is right up there.
As if Celtic needed reminding, denied regularly in derby clashes this term by the keeper. The Rangers veterans, being the only members of the current squad who knew exactly how it felt to earn title medals from their previous days playing under Walter Smith, have made sure to savour the club's 55th title, secured prematurely, in March.
At Parkhead, meanwhile, Celtic's players of an experienced vintage can certainly be cast in an unfavourable light when compared to McGregor and Davis. The slow disintegration of captain Scott Brown and loanee Shane Duffy - whose humiliations in a Hoops' jersey bordered on parody at times - practically screamed of the degree of static, self-satisfaction oozing from Glasgow's east end.
There are, incidentally, a mere 175 days separating the respective ages of Davis and Brown. One of the obvious conclusions from last Sunday's 4-1 rout by Rangers over their old rivals was the wider gulf between them. Compared to a regal, effortlessly productive display by Davis, Brown was a forlorn sight as play passed him by; punch-drunk on a nine-count. Then of course, there is Duffy, who has just returned prematurely to Brighton, a £3m loan flop. 'Duff Luck' for the Derryman, a mere stripling at 29, put in the shade by Ibrox counterparts several years his senior.
If Mr Consistency Davis does clinch the player of the year prize, it would explain one fabled maxim at least. For the seemingly ageless, you're never too old.
