When I left news media I had similar feelings. I realized I learned a lot more than I thought I did because the fast pace never gave anyone time to appreciate what they had created. Being a 24/7 type gig, you could never stop and smell the roses…now you can…and you’ll get credit for it rather than “the staff.”
And when it comes to writing, by biggest hurdle is always feeling like I have to write long, deep articles that mean something. Not true. Even a paragraph a night about something you did/saw that day is enough. The “big news days” will come naturally, you don’t have to seek them out anymore.
