[part timer]

I am late to this thread and new to Forex, so very interested in what people have to say. Developing own system sounds very good and all, but one drawback I see is that it is like reinventing the wheel.

I am considering getting a mentor to 'teach me the ropes' and then go on from there to study and learn more on my own and develop and modify things to fit me. I have read descriptions of some systems but they are either too breif/difficult to understand or they rely on trading times that apply to North America (I am in Tokyo). Being a part timer, with limited times to trade, I want a system that I can use.
Any thoughts on this? (This = getting a mentor; using limited trading times)
