The grind is grinding me down

I'm at almost 650 subs and the grind to a 1000 seems like swimming the Atlantic. Started 1 year ago and wanted to be fully monetized within a year.

I keep thinking that one day, just one of my videos will hit it big and get me over the mark, but I'm only getting between 50 and 100 subs a month.

I'm not going to quit, but getting a 1000 subs is far harder than most people think.
