Put a nice picture of your boyfriend/girlfriend as a screensaver on your phone. Preferably half naked. Be thou single so put some other half naked person whom you likest. This will cheer you up every time you press your phone even when you are only checking the clock. I was annoyingly, stupidly tired in school today... but every now and then I could very easily press to see that picture. Mhmm. In retrospect: it was a good initiative.
