It's been a good 2 years for me and I am still considering myself a beginner:) I think it's more about the daily amount of time spent to learn and practice trading.
It is common that people want to learn but do they really? I mean I have seen so many people who claimed that they want to learn but then I have seen a lot of people who ended up being a little bit different on the long run. I think it would be smarter to end up with something that is a little bit different in the end and that's the point.
If you say you want to learn but you do not do anything that proves that you want to learn then you are not really trying to learn and do not want it enough. If you really want to learn then you will, doesn't matter how long it takes, you will be a great trader eventually, but the fact is simple that you are not going to end up learning it in the end at all, most just want to get rich quicker than that.
