Yes, everything is possible. There is no amount of time that will make you a master of poker. There is some prerequisite work about figuring out the math of certain situations that you seem to have started. You need to periodically come back to that as you become more sophisticated in your play, but this pales in importance when compared to the need for discipline.
So track your results and be honest with yourself. If you are losing money, either you know what you need to do to improve and reverse the trend, or you don't.
