---When feeling depressed for a multitude of reasons, watch super geeky Paul Gross music videos.
(Because that way you can laugh, gush, laugh some more, and er, laugh again. I liked Paul Gross for his good looks and talent. I love Paul Gross for his being a great big goofball. I am aware that's not the normal way of things.)
---Don't take things so personally. Easier said than done, I know. Especially when things may seem like a direct personal affront.
(This applies to more than school.)
---Enjoy as much as you can! Seriously. Hedonism is the way!
