Will It Make the Train Go Faster?

I did bedtime stories with the kids last night, hunted for a toy plastic snake to put into the bed to calm the 3 year old down, dealt with a call back from 3 year old who had changed his mind and no longer wanted the toy plastic snake ..... rushed to pack bags, and then headed off to the train station to go to London for some coaching I was doing today.

Only to find the train was cancelled.

Next one was over an hour's wait and would get me in well after midnight.  Should I hang around or change my plans and drive instead?  A pretty dull, petty decision, but one in years gone by I would have expended a HUGE amount of angst about. What I love about the "Will it make the boat go faster" approach is the simple way it cuts through the dross and focusses you on what's important:

What's my goal? Get to London the night before to get a decent night's kip so I can deliver a good day's coaching tomorrow
What will make the boat go faster? Drive there, don't hang around in the hope the signalling problems will clear up.
What's good about this? I can't do the work I was planning to do on the train, this is two hours of enforced 'me' time.

So here I am after one relaxing car journey, a good night's sleep and a rewarding day's coaching, thanks to a couple of very simple, very powerful questions.
