Don't waste your time.
It isn't gonna help or tell you anything. Instead of trying to forecast where you are gonna be and when, take a look at HOW you're going to do it. Do you even deserve to be good based on your work ethic? Are you dedicated? How much time do you put into it? Whats your short and long term plan? Etc.. If you think nothing but sitting down and messing around on a DAW will get you there, odds are it won't. Treat your music like a business.
Time means very little. If you think there is a point where you can just stop learning and 'be there' you're dead wrong.
