Teaching and training others to do what you do is a must if you are to lead sustainably and effectively. > “The thing that thou doest is not good. Thou wilt surely wear away, both thou, and this people that is with thee: for this thing is too heavy for thee: thou art not able to perform it thyself alone.” [^1] [^1]: [[Exodus]] 18:17–18 [[Jethro]], Moses’ father-in-law, speaking to Moses in response to learning that [[Moses]] was spending night and day providing counsel and judgment to the Israelites.
