Having worked as a trader, a lot of it comes not from personal skill, but just from being in the right product, at the right firm, at the right time.
Even at firms/desks that are in the right products at the right time, few people actually make 7 figures. If I'm not mistaken, you should be aware of this for a variety of reasons. I'm not convinced that making this kind of money is easier or more likely in finance than in tech.
