Hello from North Carolina. I've been on Alamy since 2014, but just started uploading in earnest since January of this year. I had only uploaded around 300 images up until then. I rarely even checked my stats until I saw a few sales (some nice ones!) at the end of last year. Before then I mostly focused on creative images for POD sales on other sites. Now I'm trying to photograph with stock in mind. Still learning but I have enjoyed it. And I now take my camera everywhere I go, looking for images that could sell. Only time will tell on that front.
Anyway, I've been reading this forum really since I started uploading in 2014 and even more so recently. So thanks for the advice already given. It's been a big help.
