Looking Back on Comics

I'm reading a book, Marvel, the Untold Story, and its fascinating. It's about the comic book company I wanted so much to work for as a child, and when I got my chance I felt I failed, so much so that when I was offered a book to draw, I was so scarred by my initial rejection that I felt I wasn't good enough and turned the famous writer down. Now I look back on my former favorite industry, and it doesn't resonate with me anymore... even if I am still an avid reader, and still do follow them, up to now. But both my interests changed over the years, and reading this book, with all its tales of unhappy artists and tense working situations, II wonder if I would have been truly happy? Or perhaps I was never meant to be in it...
