And another thing: don't go to Malham on Saturday, go on Sunday.
Spend Saturday doing fuck all.
I don't mean fuck all like 10 hours DIY, working from home, worrying about your rental empire, setting fire to your hand whatever your hobbies are. I mean, have a lie in, send the kids off to lazer quest, go for a short walk to the shops, make your self a deluxe omelette, watch the rugby sat on your sofa. Do nothing. (Your family will thank you for this later).
Then on Sunday drive to the crag in good time at whatever speed you find relaxing, people have different definitions of this.
The working week is more tiring than you might think.
