I would actually agree with you. I believe the same. Leverage is like a double edged sword so we need to be really careful with how much we should use. For me, the lower the better.
Its better to be a part timer first than leaving your job all at once. Forex isn't as easy as it seems. So see how it goes first as a part timer and if you feel you stand a good chance of being profitable as a full timer, only then go for it.
