KNOW-IT-ALL, victorious

All of the days that I wasted gazing outside the window,
Impatient frustrations let out into my pillow,
Lied awake at night while my head wandered,
And I wondered why,
Things weren't different,
Everything shifted overnight,
Went from "when boredom strikes" to "Ms. Star on the Rise,"
It was all in an instant, man,
But those four pink walls, now I kinda miss them,
man...
