I was thinking about this as I have a literature degree and in the 10+ years since I graduated I think I've read less than ten books
The degree, which I really enjoyed doing, just killed my love of reading for pleasure.
Also, when I was on maternity leave, I bought a second hand PlayStation and got quite into gaming. I've tried to play it again since but it was never the same and it just felt like a waste of time. Something about completing a new level when life felt quite repetitive (feeds, naps, walks) was really rewarding. I think back to that time with fondness.
I also remember my friend who got really into cooking after lost her job and took a few months finding a new one. She had never even cooked pasta prior to this and then she was inviting us over for three course meals. She had a real gift! When she found a new job she went right back to ready meals and take aways. She has never cooked since!
What are yours?
