[Grammar] from nine or ten years ago on ... for seven years

[ansonguy]

Three days ago, I made friends with a non-native English speaking person. I am not native English speaking either.


(ex) He said to me,"From nine or ten years ago on, I didn't work much for seven years because I was semi-retired."


I think he meant nine or ten years ago, he started not working much. From that point on, he didn't work much for seven....


Is it grammatically correct to say "From nine or ten years ago on" to connect with "didn't work much for seven years"? Thanks.

If it is really important to talk about the exact years worked (or not worked), then best to specify the years: 'From (about) 2007 to 2014, I didn't work much because I was semi-retired.'
