The most important factor that contributes to building your character in World of Warcraft is to become a professional early i.e. to take up or grab a profession like skinning or mining. Killing animals and selling their skin to others is a profitable profession that rakes in gold as well as moulds your character by leveling out, two birds with one arrow. Mining, similarly can give you unexpected mounds of valuable or demanded mineral ores that can be sold for a premium to make a killing profit and enhance your profession as well. That is the value of profession and its contribution to your character building.

World of Warcraft undoubtedly integrates the best questing compared to other MMORPG games. Quests can be used to give you a huge advantage over others. Always get hold of a quest whenever you can. Leveling a quest takes little time, but EXP gained from killings in the quest and the rewards of completing a quest have their distinct advantages like gaining some important items and of course money. Add on bonuses of quest completion can lend you greater speed and better character through becoming richer.

Usage of gears in World of Warcraft is certainly advantageous but will deplete your gold resources heavily. Investing in gears in the initial levels from 1 to 40 would not be worth the gold spent. These levels have lesser gear dependency and you can complete these levels from what you gain from the quests. Keep the gold and wisely invest in higher level gears.

Keep track and observe the drops of your kills. Humanoids in World of Warcraft drop more items and gold compared to other mobs, so, level yourself killing as many humanoids as you can.

The bottom-line is Gold, the more you have, the better off you would be, World of Warcraft or not. All the best.
