This is a major one, crossing from 3 digits to 4.
I once wondered if I could run every day for a month. Then it was a year, then two, and after that I finally started to think at 1000 days was a possibility. Just over a week away and I'll be there.
After that I can't decide if I should go for 3 years or just switch to exercising every day. I'm not sure and I have some soreness in the legs that I want to try and heal. Of course, I can't slow down too much with a black belt test in July, but after that I'll have to decide if I go down to just some type of activity every day or keep running and trying to try other things.
