Some really good points were made on here, I agree with the majority of them, but it's not like someone that wouldn't pay enough attention to the field would be able to pull it off. I spend the majority of my free time reading about the domain. I really recommend looking on sites like yihayihaa to get to know the best resources available for this niche. That's where I find the best books and platforms in general. Research is key when you want to succeed in a field that's constantly being influenced by a big number of external factors, mostly economic ones. Research is key in general, who am I kidding, in any domain.
