We all have our own way of earning gil. Some people craft, some people do BCNMs, some people play the AH like it's the stock market (buy low, sell high), some people farm, some people run casinos, and some pervy manthras cyber with people for gil. Everyone has their own way.
Personally, I've been too lazy to level any of the crafts and I have no patience with farming.
So for the past 2 years, I've basically made all the gil I've needed doing quests and selling the expensive scrolls that I get rewarded with for doing those quests.
The only other method of gil making that interests me would be BCNMs. But I don't really have any experience with these and I'm not sure what BCNM would be best for making profit, or how to go about doing them.
So what's your preference when it comes to making gil? Which strategy has proven most profitable for you?
