Well, I'm a new architect myself and still full of enthousiasm.
I think the best way not to get bored is to have friends, with which you'll be able to share your views on architecture and to have light discussions in your free time.
A trip allways helps. Organising short holidays to foreign places is the best solution, because you can combine "bussiness and pleasure". You will rest, escape from your routine and you'll get to know better the architecture of other cultures, which is allways revitalising! That's what I personally do and when I return I'm filled with new ideas!
