Do all things without murmurings and disputings.
Phil. ii. 14.

He that hath no rule over his own spirit is like a city that is broken down, and without walls.
Prov. XXV. 28.

Behold, the paths of life are ours, — we sec
Our blest inheritance where’er we tread;
Sorrow and danger our security,
And disappointment lifting up our head.
Anna L. Waring.

ONE valuable way of practising self-control is in checking grumbling, and an unnecessary display of vexation at petty inconveniences. A workman has fulfilled his task imperfectly, some order is wrongly executed, some one keeps you waiting unreasonably; people are careless or forgetful, or do what they have in hand badly. Try not to be disturbed; be just, and show the persons to blame where they are wrong, even (if it be needful) make them do the thing over again properly; but refrain from diffuse or vehement expressions of displeasure. A naturally quick, impetuous person will find that to cultivate a calm external habit is a great help towards gaining the inward even spirit he needs.
H. L. Sidney Lear.

A repining life is a lingering death.
Benjamin Whichcote
