Try not to listen too much to lecturers/past students when they tell you you'll be spending your whole life studying - unless you're doing something really demanding like engineering or law you won't be. I've done a number of different areas (sciences and humanities) and I have friends/brother doing different ones again and frankly the projected study amounts are really inflated, and past students always say they worked far harder than they actually did. So don't stress too much about that.
However study motivation tips... well lots of people say it's important to have some special study area with no distractions etc - I study/do essays etc on my bed. Not very good for my back but it hasn't hurt my grades

. Take lots of breaks too. If you go too much longer than half an hour your attention will wander and you may as well not be there anyway. Especially if it's especially boring. Like for instance I have an ancient history essay that I'm almost eager to start writing because I can tell it's going to be a masterpiece (heh

), but I was trying to write the intro to a psych report yesterday and I couldn't focus, it was so dull! So obviously do as much as you need to but space it out, and don't do too much in one day.
And don't overstudy! Even the most interesting material gets deathly if you read it too much. Try to time studying for exams so you don't get to a few days before and you're so sick of the material you just can't make yourself read it anymore. It'll be obvious soon enough how much you have to do to do well, so next time, do that much and no more.
Hope you do well [img]smile.gif[/img]
