How to grind your skills (Griding guide and list)

Grinding your skills should be an easy task. You just have to use the skill, right?

Well, in most cases you really just have to use it (Activate it). Like using the procurement skill. The more you use it, the more proficiency you will get.

In some cases you just have to click on it to "use it", like surveying.
Some will require you to perform a specific task, like talking to a NPC (Body Language).
Some skills are passive, like sail handling, steering and navigation. So you just need to sail around to get proficiency.
In other cases you have to be careful with its specific requirements. Like survival, you need to watch the requirements that will trigger actual proficiency.

And on top of all those particularities you can make a poor choice of place to grind. You see... no grind spot was made equal and some will give more prof per hour.

Going back to the procurement example, it turns out that what you collect greatly affects the proficiency you get (Or don't get).

So taking that into consideration I created one guide for each specific skill. It is currently arranged in blocks until I finish all the skills:

Note: Grinding your skills will not reduce the amount of skills you can have at the same time.
