I have always believed that the core characteristic that best defines those who we aspire to be like is self-confidence. Our musical idols are who they are, they speak their mind, and they communicate these beliefs through their actions and the sign posts they leave on the road they travel. Some more recklessly, some more elegantly. They are not perfect, they are not above failure, they are not people whose lives have been free of adversity. They are people who have taken lemons and made lemonade. Their character and will to succeed drives them. Oh ... and they also put the hours in to make it all happen.
Speaking as someone who travelled from the top left-hand corner of the world to New York to pursue his dreams, I can say confidently that most of my professional successes have come not because of my technical acuity, but due to my musical character. The choices I make in studio sessions, whether from behind the kit or behind the board, are reflections of my interpreting what i'm hearing, what I am being asked to accomplish, and how best to achieve it. Music is family, everybody needs everybody to achieve results.
The only thing that really matters at the end of the day is how you make listeners feel. They want to hear your voice, your words, your musical phrases, your specialness. Your character is what's going to pique their interest, your truth is what's going to stir their emotions. Character is all about being perfectly imperfect, about individuality set on a background of opportunity. Resonate, and your listeners will vibrate at the same frequency. For those succeeding in the music industry, whether artists, instrumentalists, or those driving the business forces working their magic, character reigns supreme !
