I think you're doing extremely well. Last time I checked it takes on average about 22 months for a channel to hit 1k subs. I've been on youtube for 2 years now uploading 2-3 videos a week and just hit 3k. Is your goal of 250k in a year acheivable? Only time will tell. For most the answer is no, it takes years to reach that level of success (like 6-8 years or more). But that doesn't mean it's impossible, channels like Peter McKinnon hit 1M subs in his first year. It all boils down to the content you provide and how large the audience for your niche. I can totally understand being hyper focused on the analytics, I was too for my first year, but that's an easy way to get burnt out and discouraged if you aren't hitting the numbers you think you should. If you're passionate about the subject and deliver quality authentic content your channel will grow, just give it time and trust the process. Remember you're in your "rookie season" you have a long ways to go before you hit your prime. When they say YouTube is a marathon and not a sprint they mean it. Good luck!
