I've followed a lot of cricket and football over the years and noticed that a certain kind of positive mindset can get surprising results e.g 'Bazball' so I've tried to challenge myself to weed out unnecessary negative judgements and I do think that had improved my productivity (I get that sometimes that stuff is cringe).

I've developed a personal view of freedom which makes space for joined-up decisions over years and decades, whereas before I had a strong prior on anything which didn't feel good being an insult to my liberty. As a by-product I am more productive now, but it had to happen in that order.
