My New Year's resolution was to write more and I'm happy I was finally able to find the time and start my own newsletter on substack! (I write about engineering management at engmgmt.substack.com) So far, it's been challenging to find the time to write frequently -- once a week is recommended but I'm aiming for once every two weeks.
For those on the fence, writing is a wonderful hobby that also has some practical applications -- give it a try!
