Never focus on the numbers.
They can be experience bar, character level, item level, damage per second, gold etc.
It will make you anxious, and at a point you will start to get bored of the game extremely fast.
Grinding in a MMORPG is the worst thing you can do. Killing the same monster over and over is boring and no one wants to do that.
Always do something
You can open the map and look where there are quests.
Usually games provide a set of dailies, so you will probably never run out of content you can do.
If you feel like doing a dungeon or battleground you should queue right when you start your gaming session and continue doing something else to never wait.
It’s easy to find content you can do
The developers spent a ton of resources trying to figure out how to make people stick for as long as possible to their game. They made a clear path you can take and made sure you can discover most of the content by yourself.
First of all there is the leveling content, there are quests all over the map you can do.
Most of them have enjoyable story that you can get immersed in.
Leveling dungeons have a unique design and you can explore them without needing other people, same like leveling zones, you can go and make some great screenshots for your collection or to show to others.
The achievement system is something huge. Developers placed interesting things all over the game and gave up hints on how to find them through the achievement system. You will probably never run out of achievements any time soon. Only less than 1% of the game’s population probably has every single one of them so you will get a lot of time of fun out of them.
Making gold or other currencies
Getting gold is easy if you play the game a lot. As I mentioned before, never focus on that number, instead focus on the enjoyable gaming experience.
If you constantly do enjoyable stuff in the game, gold will come to you without any grind!
The secret to having more gold, is to never spend it, you can just think twice about stuff that you want to buy and you will probably double your total gold just by being aware on what you spend it on.
Have a few alts
Did you see how cool that new released class looks? You can create that type of character too!
Leveling new characters can be extremely fun, you can see what their spells are, what animations they have etc.
Always talk to other people
The point of the MMORPG genre is to socialize with people, so, just do it.
Is super easy to find someone to talk to, just go outside in the world, do something, and if you see someone, say “hi” and then ask how they are, tell them what you are trying to do etc.
Then ask them if you can add them to your friend list and BAM, you have a friend now.
And the next time you log on the game you can just look in your friend list and find people to talk to.
There are some times when people will be assholes, but try to avoid them.
The first time you will do this, it will be harder, maybe you will get one in five people to be on your playlist so don’t stress out about it.
