Wealth and fame are like alcohol: they don’t make you happy. They can only augment happiness that’s already there. If someone isn’t happy before getting drunk, they don’t become a “happy drunk”.
I find it helpful to listen to .mp3s of people talking about something I’m interested in. I can focus on that and drift off to sleep and wake up not even realising I fell asleep. Also, I’ve found a hindu mantra that helps sometimes. It’s so hypnotic, it just carries me into the navel of sleep.
