When I first started programming, I fell in love.  Over a period of roughly 3 months, I maintained what can only be described as a productive mania.  I had a very positive mood, elevated energy levels, intrinsic motivation, and an overwhelming, driving, sense of happiness.<p>I would spend hours, and hours, pouring over documentation, absorbing everything I could.  I applied what I learned in projects that were relevant to me.  Every day I was EXCITED to wake up, and learn more.<p>That was 5 years ago, and I still look back on that time and wonder HOW?  HOW did my own body, naturally, without drugs, go into a state of HYPER productivity and HYPER positive mood?  Is it not possible to induce that state again somehow?  If I was capable of it once, why can&#x27;t I control it?
