I just saw this inspirational blog post by Paul Buchheit Here’s a quote:
Forget about your lack of talent, skills, knowledge, time, resources, or whatever else you need to be “good enough”. Start an inane blog, take bad photographs, upload boring videos to YouTube, write bad software, create useless products, play bad music, and make ugly art. Forget “good enough”, and then simply indulge in the joy of creation.
He also states he likes xkcd :)
