Do job *exclusions* define your character, and how?

As I mentioned before, I may not roleplay (at least not as much as I used to), but every character I make has a story to them. Thus I usually try to have each character assigned to a job/class that suits them the best. For example:Kindhearted Xiaoyu's never going to touch Dark Knight with a 30ft pole, but Xiaomu's giving it the old college try. Tech geek Xiaolu's main class is Machinist, but is also trying Gunbreaker and may likely give Sage a go as it seem to be somewhat technology influenced.

I like to be at least competent at everything so I usually level up most things except WAR, BRD, DNC and MCH ( altho I am leveling MCH now ).

But as far as my character '' canonically '' goes I think of her as a martial artist who likes to fight hence MNK main but also skilled as SAM and NIN too.
She just prefers to fight with her fists.

I think that playing everything is good tho because it allows you to understand what other players are doing more and makes you a better player.
And there's a lot of overlap too.

Edit: Also I prefer to think of my martial artist characters as more '' magic '' based, in the sense that they're not huge muscle mountains of doom and that's why they can punch hard.
They can punch hard because of '' Chi '' basically, and NIN plays into that too since they have magic so I think there's some overlap there thematically.
My character is more strong because of her spirit rather than because she's a gym rat.

I guess maybe you could read that into me playing the other Jobs too, because I want an understanding of others around me and the whole and that makes me a better MNK.
