Using a different lanuage such as latin makes the mind work, and thus uses more energy and focus. If you do things in simple english(or whatever your native togune is) then there isn't as much effort into it, and thus is not as powerful.
Now, yes magick can be complicated, but it can also be simple. Ultimately it is up to the user and the purpose in which they're using(and by no way did I mean that in a wrong way, lol).
But you all are forgetting one MAJOR thing(and yes you'll see this in a lot of my other posts). Insted of doing things the magickal way, how bout try the mundane way first. More miraclous things have been known to happen if you only try. Everything does not have to be done using magick(nor even require it).
Loads can be done with simple will power, determination, skill, and desire alone(and sometimes some natural talent helps).
So ya, them thee breaks,
