Dalai Lama: A to Zen in Life

Ok. So I'm sitting at my desk all day trying to study and understand developmental psychopathology for a test that I have tomorow. I like the class and find it very interesting. The interesting part to her test is that she asks us to apply the concepts to real life. Thats OK, I mean that is what we are trying to learn and eventually we will have to do that in the future. The challenging task then is how to apply it, I mean we need to know facts and we need to know different situations.
The lectures point out key information, in addition we have a boring textbook that has no diagrams or pictures, and she says, If I dont' mention it don't worry about it. Ok but if you mention it in one sentence do we have to know all about  Ainsworth attachment theories, and the types of parents there are.?
I have a poster in my room that looks like this:

It has an inspiring quote or something to think of with each letter. B is Believe in yourself.
So when in doubt, when your worried or stressing about anything, realize that you many know more than you think you do. You may have to push yourself a little harder but it is possible. If you don't believe in yourself, who will? I challenge you, when you are facing a difficult test or situation to say something positive to yourself and believe in yourself.
