First of all, it is good to know that trading is not for everyone. It is better not to trade than to be losing money. Anyone that has been trading for like a year and is losing, it is better for the person to stop trading.
A year in trading isn't even enough to experience what the market is, except you have dedicated your entire time to learning and experiencing the market first hand, then I'll say in two years, with the right knowledge and enough capital you may be able to kick off on your own. Most people have this mindset that once they go into trading, they would become millionaires in probably a year like you said... But it's not as easy as many thinks.
Trading is a marathon not a sprint. Meaning if you want to archive success in trading for the long term, then your plans should as well be on a long term goal. Any thing short would tarnish your plans of being profitable in the market.
