Simple things.
I'm eating better. A bit more veg and salad. Fewer processed foods.
And I'm able to enjoy reading fiction in Spanish now. I love reading fiction but cannot easily justify the time spent on novels. If I read in English, it's either theory or for work. But I told myself that I could read fiction if it were in another language. So I started learning Spanish. And at the start of this summer I got through my first full novel. I'm on #4 now, and while I have to check the odd word, I can more-or-less breeze through (at a slower pace than I read in English). So now I can read fiction and improve my Spanish at the same time. It's been fun, but it is a bit of a chore in the middle, after you've learned the easy bits, but before you can fully enjoy native content.
