Farm in World of Warcraft for right or easy way

In World of Warcraft, there are many methods that regular WoW players can farm in order to get excess of gold. Physically, there are many ways that you can earn a lot of gold by farming, raiding, using the auction house, selling area team, taking players into raiding and so much more. But mentally, there are only a few ways. For example, stick with something that you're good at and it won't let you get bored. Once you are not bored, you can perform the task longer because you are enjoying what you're doing. In addition, you can set a higher goal and a better motive to continue gold farming. All can be done just because you are not bored!
Keep the ideas of physical and mental when you go farming for gold.
Definition of Farming: The camping of spawn points to collect in-game currency or items or to repetitively perform tasks that create in-game currency or items. Common myths about farming:
> There is no one right way to farm.
> It is not reserved for DPS - Healers & Tanks can do it too.
> You do not need specific professions to do it, though they help.
> You do not need to be asian, or otherwise located in an asian vicinity.
Keeping these short and simple rules in mind, you too can have enough gold on hand to afford those on-demand consumables for those long progression raids, or even those hefty repair costs you plate wearers manage to accumulate. With the changes made from patch 3.0+ and the addition of WotLK - the rules haven't changed and income has only gotten easier. Time still = gold, and dailies are still a huge, steady income.

1. Stick to what you're good at
2. Set a goal
3. Have an motive
4. Do your dailies
5. Do your homework
6. Use the auction house
7. Time = gold
