No matter how accomplished a craftsman is, there is no bigger motivation to keep going than honest appreciation from people who care about the craft. That article you liked by someone on the Internet could be their last before they were planning to give up on writing. So if you really, honestly and genuinely like something that someone has taken the effort to share with the world, all it takes is one tweet, one like, one email or one comment to keep the fire going. So do that one thing today.
