One good thing also is : take a break while tou can and still aren't disgusted with the job, letting also the door open for a later come-back.
The worst thing to do is to thin the rope until you're completely fed up with NT jobs, player formation or even worse, the game itself.
I remember that I went a mandate too far last time and I still haven't gotten my interest for NT back - I hope this will be back anytime soon.
yh, my last mandate was one too many too :P i've managed to come back for our U21, but i was happy as hell that Benovic was willing to take over. it has given me a new opportunity ^^
