Scott Berkun, on How To Be Creative:
Want to be more creative? Pick a problem you care about and get to work. If you don’t care about anything, your problem isn’t creativity, it’s apathy. If you start things and give up, your problem isn’t creativity, it’s dedication.
Few people in history that we call creatives today read books or took courses on creativity. Instead they apprenticed with masters in a craft and worked with them. They did the grunt work until they had the skills needed to do more sophisticated work. They learned how to develop ideas and deliver finished work by working. There is no other way.
Don’t believe me? Pick any creative hero, and any creative work they’re famous for, and investigate how many sketches, or drafts, or attempts they had to make to get it right. They may have had flashes of insight here and there, but those came while they were working their asses off. Ideas are cheap, it’s the passion to make ideas real that’s rare.
