The LORD helped me with this when I was first ordained by arranging that I be in my forties and more able, therefore, to withstand some of the pressures that might have swept my 25 year old self into full blown workaholism and burn out.
He also helped me by bringing my attention to Psalm 127 early in my ministry.
Unless the Lord builds the house,I realized that my parish was His to build. I am to work hard and do an honest day's work, but in the end, He must do the building. If my church was to grow because of 60+ hour weeks on my part that would be a false growing.
those who build it labor in vain.
It is in vain that you rise up early
and go late to rest,
eating the bread of anxious toil;
for he gives to his beloved sleep.
