1. Endeavor, My son, rather to do the will of another than thy own.
2. Ever choose rather to have less than more.
3. Always seek the lowest place and to be inferior to every one.
4. Always wish and pray that the will of God may be entirely fulfilled in thee.
If I might be so bold, I'd like to add that a fifth thing which brings peace, at least to our family, is spending time in the great outdoors, enjoying and marveling in God's beautiful creation.
Having fun as a family, enjoying the company of friends and, yes, even getting some exercise. I hope you've had time to get out into nature this summer! If not, hurry up while there's still some summer left :)
