Moses' father-in-law Jethro gave him the earliest recorded leadership advice in Scripture — and it was about hiring. The criteria: capability, fear of God, trustworthiness, and integrity around money.
Notice what's not on the list: impressive credentials, personal likability, or availability. The non-negotiables were character-based.
Skill without character is a liability. A talented person who lacks integrity will cause more damage than a less talented person who is trustworthy.
Slow hiring and fast firing is a painful but accurate maxim. Take your time. If you've hired wrong, don't delay a necessary correction out of discomfort.
