I just finished my college career (till i have to go back for my masters, but that will be different and a few years from now) in December and it was definitley harder then than it is now. I went to school for teaching and currently work as a substitute teacher. This is the part that sucks about my job. I dont know when I will be working or where (granted its all in the same town) or what grade I will be teaching on any given day. I think that one of the bigs things, like Amy said would be to pace yourself. I think my subbing is helping me, b/c eventually someone will see me and want to hire me (or at least I hope thats the case). BUt at the same time it is getting me 'ready' for a full time job. Since I usually get called the night before I have to work, I am able to set my alarm and do my morning routine before school. If I dont get called the night before, I have accustomed myself to wake up at a certain time...its almost like im afraid that I MIGHT get called, so I wanna be ready. So even if I dont get called to work, I am usually up. This helps me to really stay in a routine because I find that if I fall out of a routine, then I will get sicker or I will more tired.
Hope you figure something out soon!! Good luck!
