We're all familiar with the story of the Tortoise and the Hare and we're usually told that the moral of that story is that 'slow and steady wins the race'.
Well, I think that's rubbish.
It's the wrong lesson in my eyes to take from the old fable. Rarely does going slowly help you to win any races. Slowly might be a good way of being careful, but it's not what races and competitions are all about.
The Tigers are the hares of this year's Betfred Super League and they've got off to a brilliant start. They've sprinted faster than all the rest to have 36 points on the table already.
Four more wins from their remaining nine games would give them the League Leaders' Shield for 2017, an amazing achievement in its own right.
If last year was anything to go by, two more wins would guarantee them a top-four finish and a 50/50 chance of appearing in their first ever Grand Final. How many Tigers fans thought that was going to happen this year?
What could go wrong?
Castleford's confidence is such that they believe that they can beat everyone else at present, and their performances this year deservedly provide that belief. I see their only problem being one of over-confidence. Their own attitude is their biggest challenge at this moment.
If you cast your mind back to 2011, Warrington Wolves were in a similar position. They topped the table, lost just five of 27 games and scored over 1000 points. That year's tortoise, Leeds, after finishing fifth managed to catch up to them and then sneak past them with a late penalty goal to win the play-off.
Transfer your memory over to football and you may recall in 1995/96 season the 12-point lead that Newcastle United had when Kevin Keegan's team were playing with such brilliant style. They were the round-ball equivalent to the Tigers in attack and people from all over the country loved to watch the way that they played.
There were Christmas cards printed with Newcastle players holding the Premier League trophy and they topped the table from August to the end of March.
Eventually, they were caught by the team from Old Trafford who won 13 of their last 15 matches. It just goes to show that sometimes it's the ones out in front who feel under the most pressure.
Last week's comeback at Wakefield was the equivalent of Kevin Keegan's 4-3 defeat at Liverpool but on this occasion, the table toppers held their nerve. It was great entertainment.
The big question is, can they keep it up until October? If they fall asleep once between now and the end of the year, hoping that their ability is good enough, without proving it with their efforts, they might get overtaken and finish the season like Newcastle United did in 1996.
I think that the real moral to this old fable is that success depends on using your talents, not just having them.
