Sorry, have to point out that it's 3rd person imperfect "C'était" (because the 'était' is referring to the "c'" ('it') not you
Yikes, interesting ideas you have. I'm 17 and manage to concentrate for more than 30 mins...?
OP, we need language teachers. I'm studying German and French (and English lit) at A2, and (sent me application today) for German + linguistics at Uni, but only
600 people applied for German at Uni in the UK last year. That's terrible (but possibly good for me at the moment!)
Having the class's respect is the most important thing, because then they will do whatever you want even if it's work.
It seems to be the teachers who have a 'human' side that the students like best. For example, if the teacher is clearly a very different person around their students than at another time, it tends not to work, as neither the teacher nor the students is / are comfortable and everything is a bit on edge...
Not sure about giving time to 'relax' though. Sure, time to discuss things, maybe about the subject, maybe not, but WITH THE TEACHER, NOT just time for doing whatever you want. Having an involvement with the students is crucial; they have to have a relationship with you that extends beyond just being taught and being set homework. If you can be in a situation where there's a mutual respect, you win, and so do they
