The obscenely talented Seb Lester (Type designer and Calligrapher) discusses dedication to his craft & the importance of passionate practice (self initiated work) in this excellent interview on booooooom

"At this point in my life I want to focus on art. I’m extremely interested in seeing what I am truly capable of producing as an artist working with letterforms, without all the constraints associated with client work. I obviously need to make a certain amount of money, but it’s not a prime motivator. It’s much more important to me that I try and fulfil my potential as an artist."

"I am personally more interested in trying to become a true virtuoso in one field than a generalist."
