I wouldn't mind that promise thing if it was more of a productive means to help your idol. It's just like the self lessons, it's just easier to do the lesson manually then try and time it exactly to pull your psp out of sleep.
Speaking of bugs/glitches, I don't know if anyone has experienced the one where the game loses track of text and your idol is stuck bobbing. I had that happen several weeks after getting PS. Pulled the UMD out and put it back to see if it could fix itself, but it didn't help, I had to exit the game. Fortunately I haven't been able to pull the glitch off again but makes me wonder if it was a glitch in the game at all or just my psp acting funny that moment 
Yeah, doing self lessons, I never understood doing XD Plus the lessons are kinda fun to do, so why skip 'em?
and, oddly enough, that same glitch happened to me a few days ago! I started a new storyline with Iori and she just was left sitting there. I was pretty worried when I discovered that none of the buttons did anything (I thought my PSP broke right then and there XD) but after shutting it off, it worked fine and hasn't happened again.
