Too bad the guy self-destructed.<p>For the longest time I was incredibly frustrated because I couldn&#x27;t &quot;play&quot; guitar.  In other words, my life was about very strict technique development and playing from scores.  In the meantime, some of my friends could just grab a guitar and play great sounding rock and roll riffs.  I simply couldn&#x27;t do that.<p>Until one day I could.  I mean, I could play anything.  And my repertoire expanded with ease.  And my friends were still playing the same ten pop songs five years later while I could approach just about anything.  The difference was effort and discipline.  I think the same applies to anything, be it music, engineering or business.
