1. If you have 3 minutes: Read this great hashtag.
Emerald Street is a great daily newsletter – you should sign up! – and they asked their readers to submit one "small good thing" that cheered them up. It's a delight to read.
2. If you have 5 minutes: Take a screen break.
3. If you have 10 minutes: Get some career advice.
4. If you have 15 minutes: Read this excellent piece about what to do when you're blue.
5. If you have 20 minutes: Get off a stop early.
Walk for a lil' bit! Or if you're in a city that has public bikes, such as London, sign up and zip around the place.
"I've been taking a Boris bike instead of the bus/tube if at all possible – most places I want to go are less than 30 minutes away (which means there's no extra costs) and it often takes the same time as it would using public transport anyway. So it's a triple whammy: cheaper, healthier, and a great way to see more of the city, even if it's the bits you usually go past! The other thing about using the city bikes is that there's no maintenance – if you get a puncture, just park it up and forget about it!" – Jordan Ballantine
6. If you have 30 minutes: Swap a book with a friend.
One of my favourite ways of finding new books to read is by asking friends and family. For example, my brother loaned me The Bees recently and it's so good! Ask your bestie to lend you a book, and you won't be disappointed.
If you prefer to find your reccs online, then Goodreads is a great place to start.
