I currently have a small channel of ~150 subscribers and 75,000 total views. A lot of my videos are preview videos for game mods, and I post videos at least 2 times a week if not more, lately I've been posting more like 4 times a week. At the moment I earn the majority of my income from my videos being embedded in these mods' descriptions. I earn about $5 a month right now. My question is, how can I efficiently grow my channel in a timely manner? Over the next 1.5 years, I want to save up $5000 from YouTube so I can buy my first car and pay for its expenses. Is this a realistic goal? If so, how can I go about working towards it? Thanks.
