Deep Work

While not a Biblical resource, the following book gives practical advice. When integrated into the life of the believer in concert with God's Word, priorities can shift, focus can be narrowed, and space can be made for more effective and efficient ministry. 

"Deep Work—the ability to focus without distraction on cognitively demanding tasks—is one of the most important abilities you can cultivate in our current moment. It’s a skill that allows you to quickly master complicated information and produce quality results in less time."
