I personally think starting with geo domains is not the best way to get profit and of course neither to get fast experience for a newcomer. I have learnt a lot making mistakes and reading and chatting a lot here, which I made lot of friends, but I would suggest start studying which niches are hot nowadays and try any handreg, try register brandables from 5 to 7 characters, no hyphens no numbers, and see how it goes. The more you read here the more money and mistakes you will avoid. BUT! I think the best way to learn after the reading here option , is registering some domains and learn how it goes, when you feel you are loosing money, it will hurts, then you will pay attention and become better and better step by step.
To sum up, I repeat again, don’t think would be the best option for a newbie to make outbound with geodomains. Study the main tdl’s, register any .net .org according to the sales at namebio, namepros etc... I am not a master domainer, but the little exp I learnt was on that way. Peace.
