A post here builds around Napoleon Hill's concept of a definite chief aim, using a real personal example, performing again after more than half a year away from the stage at a friend's concert in Atlanta, to argue that loving what you do is a discipline rather than luck.
The two etiquette posts are the most specific writing here, drawn from years of watching performers on stage, warning against an artist's entourage overwhelming a show and cataloging the exact phrases, turn my mic up, turn the music down, that signal a poorly run sound check. Both etiquette posts credit personal observation rather than secondhand advice, giving them a level of specificity most music blogs skip entirely.
None of the three posts describes a specific gig gone wrong in full detail, staying at the level of general lessons drawn from many nights on stage.
