I think everyone starts out with a dream like that. But reality sets in rather quickly. If you don't make it early on it is highly unlikely you will get big later on with the same content. I myself have been at it, in my current format, for 3 years now. Inching closer to 5K subscribers, and have over 1.1M total channel views. Unfortunately this is no real success in the eyes of most. Most see success of a channel at 100K subscribers and 100M views. Even YouTube does not recognize anything below 100K subscribers. No bronze plaque at 10K. Nope, you need to hit 100K or bust.
To answer your question: No, I don't see myself growing big. And that is because I am a realist. I also treat it as a hobby now, no longer pushing to create content every week. One or two videos a month and that's it for me. Never been happier. Although, it would have been awesome to hang that silver play button in my man cave. A sense of accomplishment.
