'only ten seconds, no one is that important', eh?
Sitting in the outside seat, by the doors, gets me off the train first. Otherwise I'd have to amble slowly behind the enormous wheely suitcase brigade.
I sat in the right carriage, so those doors stop right by the bottom of the stairs.
This means I get up the stairs first, so I can take them two at a time, and change platforms in under a minute. Otherwise I'd have to follow those poor souls who are slow/lazy/texting/slurping/wearing unsuitable footwear, meaning they take the stairs at a snail's pace.
This means I catch the service which leaves a minute after my train arrives. Otherwise I'd have to wait a further ten minutes for the next one.
This means I get the quick service which doesn't stop. Another four minutes saved.
As it is the quick service, I can stand by the doors, because the first stop is where I'm getting off. Because I actually pay attention to what is going on around me, I am carrying my rucksack instead of wearing it, so I can move to let people past if they need to get past. It also means I have hands free to help anyone struggling with pushchairs or massive suitcases, because I am not a twat who just stares at people instead of giving them a hand.
This means I am first off the train again, ready to take the stairs two at a time. Otherwise it is another three minutes with the slow/lazy/texting/slurping/footwear brigade.
At the top of the stairs I have my ticket in my hand, ready for the barriers. The right hand, because that is the side the slot is. Because I got there first, it is a smooth transition out of the station. Otherwise, another minute waiting for those of us who didn't think that they might need to use their tickets despite being told so on the train to fumble about in their bags.
All these things add up to a saving of about 20 minutes. And that's just on the way to work.
20 minutes every day: that's an hour I can spend doing something more useful every week.
Say, for instance, leaving work a bit earlier, so I can catch the fast train home, which arrives 45mins earlier than the next train, and join in bathtime with my daughter.
Sure, it's not heart surgery, but all those tiny savings add up to something that matters to me.
