I stencilled a Latin quotation "ars est celare artem" (roughly translated as - "true art conceals the means by which it is created") on the wall above an archway through to the back of the house in the hallway at a previous home.
This was in 1999/2000, so I believe it predated the current trend which I can't stand personally, for two reasons really - 1) most of the phrases are too bloody obvious in what they're telling us to do - like we don't know the point of a bath is to "bathe"! and 2) every other person seems to have them, thus showing they have little imagination to do something that bucks the trend 
Our decorating/furnishing is very much in sympathy with the Arts & Crafts Movement when these quotations appeared fairly frequently - on furniture etc - so it seemed fairly apt. We have also both been designers so again it was a nod to that. Even so I concede that I was in no way being original in choosing to do this 
However, I loved seeing the look on guests' faces when they thought they saw the word "arse" on our wall the minute they came through the door 
By the time we moved to our last house the trend for these stencilled/sticker words had taken off big time, so despite really wanting to do something similar in Latin there, I restrained myself for fear of appearing to jump on the proverbial bandwagon.
To the OP, if it's what makes you happy and you're not just doing it because everyone else is/has, I'd say go for it!
