Wayne Cordeiro is the pastor of New Hope Christian Fellowship in Honolulu, Hawaii. In his book, Leading on Empty, he makes a proposition that is well worth considering.*
Wayne says that 85% of what we do can be done by anybody: ordering supplies, mailing packages, making phone calls, cooking meals, running errands, etc. The next 10% of what we do can be done by anybody with the proper training: running the company computer program, leading a meeting, organizing a task force, etc. The final 5% of what we do can only be done by the individual himself.
